Dental implants
Dental implants are often the best treatment for missing teeth. When a damaged or decayed tooth is removed, both the visible part of the tooth, called the crown, and the root are lost. A dental implant is placed in the jawbone so that it can fuse with your natural bone and become a strong and sturdy foundation for replacement teeth. Implants can be used to replace an individual tooth or for an implant-supported bridge or denture containing multiple teeth.
Dental implants are the closest you can get to healthy, natural teeth. They will allow you to confidently eat, smile, laugh, talk, play and enjoy all of your regular activities of everyday life without thinking about your teeth.
How do dental implants work?
Teeth restored with dental implants look, feel and function just like natural teeth. You brush, floss and visit your dentist for regular check-ups and cleanings, same as you would to care for a natural tooth.
After meeting with a dental implant dentist to develop your treatment plan, the placement of a dental implant usually involves several steps:
- The dental implant, usually a cylindrical and/or tapered post made of titanium, is placed surgically into the jawbone.
- As you heal, your implant will osseointegrate, or fuse with, your natural jawbone, with the two growing together to form a strong and long-lasting foundation for your replacement teeth. This healing process can take weeks to months while you proceed with your everyday life in between appointments.
- Once the implant bonds with the jawbone, a small connector – called an abutment – is placed on top of the dental implant to connect the implant to the replacement tooth or teeth.
- An individual tooth, an implant-supported bridge or dentures containing multiple teeth are then attached to the abutment.
Periodontal Disease
The term “periodontal” means “around the tooth.” Periodontal disease (also known as periodontitis and gum disease) is a common inflammatory condition that affects the supporting and surrounding soft tissues of the tooth, eventually affecting the jawbone itself in the disease’s most advanced stages.
Periodontal disease is most often preceded by gingivitis which is a bacterial infection of the gum tissue. A bacterial infection affects the gums when the toxins contained in plaque begin to irritate and inflame the gum tissues. Once this bacterial infection colonizes in the gum pockets between the teeth, it becomes much more difficult to remove and treat. Periodontal disease is a progressive condition that eventually leads to the destruction of the connective tissue and jawbone. If left untreated, it can cause shifting teeth, loose teeth, and eventually tooth loss. Periodontal disease is the leading cause of tooth loss among adults in the developed world and should always be promptly treated.
Types of Periodontal Disease
When left untreated, gingivitis (mild gum inflammation) can spread to below the gum line. When the gums become irritated by the toxins contained in plaque, a chronic inflammatory response causes the body to break down and destroy its own bone and soft tissue. There may be little or no symptoms as periodontal disease causes the teeth to separate from the infected gum tissue. Deepening pockets between the gums and teeth are generally indicative that soft tissue and bone is being destroyed by periodontal disease.
Here are some of the most common types of periodontal disease:
- Chronic periodontitis – Inflammation within supporting tissues cause deep pockets and gum recession. It may appear the teeth are lengthening, but in actuality, the gums (gingiva) are receding. This is the most common form of periodontal disease and is characterized by progressive loss of attachment, interspersed with periods of rapid progression.
- Aggressive periodontitis – This form of gum disease occurs in an otherwise clinically healthy individual. It is characterized by rapid loss of gum attachment, chronic bone destruction and familial aggregation.
- Necrotizing periodontitis – This form of periodontal disease most often occurs in individuals suffering from systemic conditions such as HIV, immunosuppression and malnutrition. Necrosis (tissue death) occurs in the periodontal ligament, alveolar bone and gingival tissues.
- Periodontitis caused by systemic disease – This form of gum disease often begins at an early age. Medical condition such as respiratory disease, diabetes and heart disease are common cofactors.
Sedation dentistry
Sedation dentistry is often mistakenly thought to induce sleep. In fact, most sedatives allow the patient to stay awake during the procedure. Sleepiness is a side effect of some medications, but nitrous oxide, oral conscious sedation and IV sedation only work to calm anxiety throughout the dental visit.
Sedation dentistry is popular because most sedatives can be taken by mouth, meaning no injections, no anxiety and no pain. Some sedatives work so effectively that even the smells and details of the procedure cannot be recalled afterwards. Safety and compliance are two important aspects of treatments, so sedation dentistry offers both the individual and the dentist the best alternative.
Whatever the form of sedative, it is essential to be accompanied by a caregiver. Sometimes, sedatives are provided the night before the dental visit, which means that driving to or from the appointment is not advisable.
Here are some advantages associated with sedation dentistry:
- Anxiety is alleviated.
- Few side effects.
- More can be accomplished during each visit.
- No pain.
- Perfectly safe.
- Procedures seem to take less time.
Perio Protect
Gum disease is caused by a bacterial infection that is hidden below your gums. Dental cleanings can effectively treat the bacteria, but when you return home the cycle often continues. Bacterial cells grow back in just hours after a cleaning, and toothbrush, rinse and floss can’t reach deep enough to address the infection at home.
The Perio Tray by Perio Protect gently applies medication deep under the gums to fight the infections. You use it at home for just minutes each day. The Tray is comfortable, flexible, and custom-fit precisely for your mouth.
With Perio Tray therapy, you have a new chance against the infections. In additional to healthier gums, patients commonly report whiter teeth and fresher breath. If you’ve been told that you have gum disease (gingivitis or periodontitis), ask our team if Perio Trays are right for you.
What should I do if I have bad breath?
ad breath (halitosis) can be an unpleasant and embarrassing condition. Many of us may not realize that we have bad breath, but everyone has it from time to time, especially in the morning.
There are various reasons one may have bad breath, but in healthy people, the major reason is due to microbial deposits on the tongue, especially the back of the tongue. Some studies have shown that simply brushing the tongue reduced bad breath by as much as 70 percent.
What may cause bad breath?
Morning time – Saliva flow almost stops during sleep and its reduced cleansing action allows bacteria to grow, causing bad breath.
Certain foods – Garlic, onions, etc. Foods containing odor-causing compounds enter the blood stream; they are transferred to the lungs, where they are exhaled.
Poor oral hygiene habits – Food particles remaining in the mouth promote bacterial growth.
Periodontal (gum) disease – Colonies of bacteria and food debris residing under inflamed gums.
Dental cavities and improperly fitted dental appliances – May also contribute to bad breath.
Dry mouth (Xerostomia) – May be caused by certain medications, salivary gland problems, or continuous mouth breathing.
Tobacco products – Dry the mouth, causing bad breath.
Dieting – Certain chemicals called ketones are released in the breath as the body burns fat.
Dehydration, hunger, and missed meals – Drinking water and chewing food increases saliva flow and washes bacteria away.
Certain medical conditions and illnesses – Diabetes, liver and kidney problems, chronic sinus infections, bronchitis, and pneumonia are several conditions that may contribute to bad breath.
How often should I brush and floss?
Brushing and flossing help control the plaque and bacteria that cause dental disease.
Plaque is a film of food debris, bacteria, and saliva that sticks to the teeth and gums. The bacteria in plaque convert certain food particles into acids that cause tooth decay. Also, if plaque is not removed, it turns into calculus (tartar). If plaque and calculus are not removed, they begin to destroy the gums and bone, causing periodontal (gum) disease.
Plaque formation and growth is continuous and can only be controlled by regular brushing, flossing, and the use of other dental aids.
Toothbrushing – Brush your teeth at least twice a day (especially before going to bed at night) with an ADA approved soft bristle brush and toothpaste.
Brush at a 45 degree angle to the gums, gently using a small, circular motion, ensuring that you always feel the bristles on the gums.
Brush the outer, inner, and biting surfaces of each tooth.
Use the tip of the brush head to clean the inside front teeth.
Brush your tongue to remove bacteria and freshen your breath.
Electric toothbrushes are also recommended. They are easy to use and can remove plaque efficiently. Simply place the bristles of the electric brush on your gums and teeth and allow the brush to do its job, several teeth at a time.
Flossing – Daily flossing is the best way to clean between the teeth and under the gumline. Flossing not only helps clean these spaces, it disrupts plaque colonies from building up, preventing damage to the gums, teeth, and bone.
Take 12-16 inches (30-40cm) of dental floss and wrap it around your middle fingers, leaving about 2 inches (5cm) of floss between the hands.
Using your thumbs and forefingers to guide the floss, gently insert the floss between teeth using a sawing motion.
Curve the floss into a “C” shape around each tooth and under the gumline. Gently move the floss up and down, cleaning the side of each tooth.
Floss holders are recommended if you have difficulty using conventional floss.
Rinsing – It is important to rinse your mouth with water after brushing, and also after meals if you are unable to brush. If you are using an over-the-counter product for rinsing, it’s a good idea to consult with your dentist or dental hygienist on its appropriateness for you.
Are amalgam (silver) fillings safe?
Over the years there has been some concern as to the safety of amalgam (silver) fillings. An amalgam is a blend of copper, silver, tin and zinc, bound by elemental mercury. Dentists have used this blended metal to fill teeth for more than 100 years. The controversy is due to claims that the exposure to the vapor and minute particles from the mercury can cause a variety of health problems.
According to the American Dental Association (ADA), up to 76% of dentists use silver containing mercury to fill teeth. The ADA also states that silver fillings are safe and that studies have failed to find any link between silver containing mercury and any medical disorder.
The general consensus is that amalgam (silver) fillings are safe. Along with the ADA’s position, the Center for Disease Control (CDC), the World Health Organization, the FDA, and others support the use of silver fillings as safe, durable, and cost effective. The U.S. Public Health Service says that the only reason not to use silver fillings is when a patient has an allergy to any component of this type of filling. The ADA has had fewer than 100 reported incidents of an allergy to components of silver fillings, and this is out of countless millions of silver fillings over the decades.
Although studies indicate that there are no measurable health risks to patients who have silver fillings, we do know that mercury is a toxic material when we are exposed at high, unsafe levels. For instance, we have been warned to limit the consumption of certain types of fish that carry high levels of mercury in them. However, with respect to amalgam fillings, the ADA maintains that when the mercury combines with the other components of the filling, it becomes an inactive substance that is safe.
There are numerous options to silver fillings, including composite (tooth-colored), porcelain, and gold fillings. We encourage you to discuss these options with your dentist so you can determine which is the best option for you.
How often should I have a dental exam and cleaning?
You should have your teeth checked and cleaned at least twice a year, though your dentist or dental hygienist may recommend more frequent visits.
Regular dental exams and cleaning visits are essential in preventing dental problems and maintaining the health of your teeth and gums. At these visits, your teeth are cleaned and checked for cavities. Additionally, there are many other things that are checked and monitored to help detect, prevent, and maintain your dental health. These include:
Medical history review: Knowing the status of any current medical conditions, new medications, and illnesses, gives us insight to your overall health and also your dental health.
Examination of diagnostic x-rays (radiographs): Essential for detection of decay, tumors, cysts, and bone loss. X-rays also help determine tooth and root positions.
Oral cancer screening: Check the face, neck, lips, tongue, throat, tissues, and gums for any signs of oral cancer.
Gum disease evaluation: Check the gums and bone around the teeth for any signs of periodontal disease.
Examination of tooth decay: All tooth surfaces will be checked for decay with special dental instruments.
Examination of existing restorations: Check current fillings, crowns, etc.
Removal of calculus (tartar): Calculus is hardened plaque that has been left on the tooth for sometime and is now firmly attached to the tooth surface. Calculus forms above and below the gum line, and can only be removed with special dental instruments.
Removal of plaque: Plaque is a sticky, almost invisible film that forms on the teeth. It is a growing colony of living bacteria, food debris, and saliva. The bacteria produce toxins (poisons) that inflame the gums. This inflammation is the start of periodontal disease!
Teeth polishing: Removes stain and plaque that is not otherwise removed during toothbrushing and scaling.
Oral hygiene recommendations: Review and recommend oral hygiene aids as needed (electric dental toothbrushes, special cleaning aids, fluorides, rinses, etc.).
Review dietary habits: Your eating habits play a very important role in your dental health.
As you can see, a good dental exam and cleaning involves quite a lot more than just checking for cavities and polishing your teeth. We are committed to providing you with the best possible care, and to do so will require regular check-ups and cle
How can I tell if I have gingivitis or periodontitis (gum disease)?
Four out of five people have periodontal disease and don’t know it! Most people are not aware of it because the disease is usually painless in the early stages. Unlike tooth decay, which often causes discomfort, it is possible to have periodontal disease without noticeable symptoms. Having regular dental check-ups and periodontal examinations are very important and will help detect if periodontal problems exist.
Periodontal disease begins when plaque, a sticky, colorless, film of bacteria, food debris, and saliva, is left on the teeth and gums. The bacteria produce toxins (acids) that inflame the gums and slowly destroy the bone. Brushing and flossing regularly and properly will ensure that plaque is not left behind to do its damage.
Other than poor oral hygiene, there are several other factors that may increase the risk of developing periodontal disease:
Smoking or chewing tobacco – Tobacco users are more likely than nonusers to form plaque and tartar on their teeth.
Certain tooth or appliance conditions – Bridges that no longer fit properly, crowded teeth, or defective fillings that may trap plaque and bacteria.
Many medications – Steroids, cancer therapy drugs, blood pressure meds, oral contraceptives. Some medications have side affects that reduce saliva, making the mouth dry and plaque easier to adhere to the teeth and gums.
Pregnancy, oral contraceptives, and puberty – Can cause changes in hormone levels, causing gum tissue to become more sensitive to bacteria toxins.
Systemic diseases – Diabetes, blood cell disorders, HIV / AIDS, etc.
Genetics may play role – Some patients may be predisposed to a more aggressive type of periodontitis. Patients with a family history of tooth loss should pay particular attention to their gums.
Signs and Symptoms of Periodontal Disease
Red and puffy gums – Gums should never be red or swollen.
Bleeding gums – Gums should never bleed, even when you brush vigorously or use dental floss.
Persistent bad breath – Caused by bacteria in the mouth.
New spacing between teeth – Caused by bone loss.
Loose teeth – Also caused by bone loss or weakened periodontal fibers (fibers that support the tooth to the bone).
Pus around the teeth and gums – Sign that there is an infection present.
Receding gums – Loss of gum around a tooth.
Tenderness or Discomfort – Plaque, calculus, and bacteria irritate the gums and teeth.
Why is it important to use dental floss?
Brushing our teeth removes food particles, plaque, and bacteria from all tooth surfaces, except in between the teeth. Unfortunately, our toothbrush can’t reach these areas that are highly susceptible to decay and periodontal (gum) disease.
Daily flossing is the best way to clean between the teeth and under the gumline. Flossing not only helps clean these spaces, it disrupts plaque colonies from building up, preventing damage to the gums, teeth, and bone.
Plaque is a sticky, almost invisible film that forms on the teeth. It is a growing colony of living bacteria, food debris, and saliva. The bacteria produce toxins (acids) that cause cavities and irritate and inflame the gums. Also, when plaque is not removed above and below the gumline, it hardens and turns into calculus (tartar). This will further irritate and inflame the gums and also slowly destroy the bone. This is the beginning of periodontal disease.
How to floss properly:
Take 12-16 inches (30-40cm) of dental floss and wrap it around your middle fingers, leaving about 2 inches (5cm) of floss between the hands.
Using your thumbs and forefingers to guide the floss, gently insert the floss between teeth using a sawing motion.
Curve the floss into a “C” shape around each tooth and under the gumline. Gently move the floss up and down, cleaning the side of each tooth.
How can cosmetic dentistry help improve the appearance of my smile?
If you’re feeling somewhat self-conscious about your teeth, or just want to improve your smile, cosmetic dental treatments may be the answer to a more beautiful, confident smile.
Cosmetic dentistry has become very popular in the last several years, not only due to the many advances in cosmetic dental procedures and materials available today, but also because patients are becoming more and more focused on improving their overall health. This includes dental prevention and having a healthier, whiter, more radiant smile.
There are many cosmetic dental procedures available to improve your teeth and enhance your smile. Depending on your particular needs, cosmetic dental treatments can change your smile dramatically, from restoring a single tooth to having a full mouth make-over. Ask your dentist how you can improve the health and beauty of your smile with cosmetic dentistry.
Cosmetic Procedures:
Teeth Whitening: Bleaching lightens teeth that have been stained or discolored by age, food, drink, and smoking. Teeth darkened as a result of injury or taking certain medications can also be bleached, but the effectiveness depends on the degree of staining present.
Composite (tooth-colored) Fillings: Also known as “bonding”, composite fillings are now widely used instead of amalgam (silver) fillings to repair teeth with cavities, and also to replace old defective fillings. Tooth-colored fillings are also used to repair chipped, broken, or discolored teeth. This type of filling is also very useful to fill in gaps and to protect sensitive, exposed root surfaces caused by gum recession.
Porcelain Veneers: Veneers are thin custom-made, tooth-colored shells that are bonded onto the fronts of teeth to create a beautiful individual smile. They can help restore or camouflage damaged, discolored, poorly shaped, or misaligned teeth. Unlike crowns, veneers require minimal tooth structure to be removed from the surface of the tooth.
Porcelain Crowns (caps): A crown is a tooth-colored, custom-made covering that encases the entire tooth surface restoring it to its original shape and size. Crowns protect and strengthen teeth that cannot be restored with fillings or other types of restorations. They are ideal for teeth that have large, fractured or broken fillings and also for those that are badly decayed.
Dental Implants: Dental implants are artificial roots that are surgically placed into the jaw to replace one or more missing teeth. Porcelain crowns, bridges, and dentures can be made specifically to fit and attach to implants, giving a patient a strong, stable, and durable solution to removable dental appliances.
Orthodontics: Less visible and more effective brackets and wires are making straightening teeth with orthodontics much more appealing to adult patients. Also, in some cases, teeth may be straightened with custom-made, clear, removable aligners that require no braces.
Thanks to the advances in modern dentistry, cosmetic treatments can make a difference in making your smile shine
