Dental implants are a popular and effective way to replace missing teeth and are designed to blend in with your other teeth. They are an excellent long-term option for restoring your smile. In fact, the development and use of implants is one of the biggest advances in dentistry in the past 40 years. Dental implants are made up of titanium and other materials that are compatible with the human body. They are posts that are surgically placed in the upper or lower jaw, where they function as a sturdy anchor for replacement teeth.
Veneers are thin, custom-made shells crafted of tooth-colored materials designed to cover the front side of teeth. They are an option for correcting stained, chipped, decayed or crooked teeth. Veneers are made by a dental technician, usually in a dental lab, working from a model provided by your dentist. Placing veneers is usually an irreversible process, because it's necessary to remove a small amount of enamel from your tooth to accommodate the shell. Your dentist may recommend that you avoid some foods and beverages that may stain or discolor your veneers such as coffee, tea or red wine. Sometimes a veneer might chip or fracture. But for many people the results are more than worth it.
A crown can help strengthen a tooth with a large filling when there isn’t enough tooth remaining to hold the filling. Crowns can also be used to attach bridges, protect a weak tooth from breaking or restore one that’s already broken. A crown is a good way to cover teeth that are discolored or badly shaped. It’s also used to cover a dental implant.
A diastema is an area of extra space between two or more teeth. The two front teeth of the upper jaw area is where diastema is most frequently seen. Many children experience diastema as primary teeth fall out, though in most cases these spaces close when the permanent teeth erupt.
Diastemas may also be caused by a tooth size discrepancy, missing teeth or an oversized labial frenum, the tissue that extends from the inside of the lip to the gum tissue where the upper two front teeth are located. Secondary reasons involve oral alignment issues such as an overjet or protrusion of the teeth.
Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
Does Whitening Work on All Teeth?
No, which is why it’s important to talk to your dentist before deciding to whiten your teeth, as whiteners may not correct all types of discoloration. For example, yellow teeth will probably bleach well, brown teeth may not respond as well and teeth with gray tones may not bleach at all. Whitening will not work on veneers, crowns or fillings. It also won’t be effective if your tooth discoloration is caused by medications or a tooth injury.
If you have a severely damaged, decaying tooth or a serious tooth infection (abscess), your dentist may recommend a root canal treatment. Root canals are used to repair and save your tooth instead of removing it.
Everybody gets a dry mouth from time to time. Temporary mouth dryness can be brought on by dehydration, stress, or simply the normal reduction in saliva flow at night. But persistent mouth dryness, a condition known as xerostomia, is cause for concern.
Xerostomia occurs when your salivary glands, which normally keep your mouth moist by secreting saliva, are not working properly. A chronic lack of saliva has significant health implications. For one thing, it can be difficult to eat with a dry mouth; tasting, chewing and swallowing may also be affected. This could compromise your nutrition. Also, a dry mouth creates ideal conditions for tooth decay. That's because saliva plays a very important role in keeping decay-causing oral bacteria in check and neutralizing the acids these bacteria produce; it is the acid in your mouth that erodes tooth enamel and starts the decay process. A dry mouth can also cause bad breath.
There are several possible causes for xerostomia, including:
- Medications. For most people suffering from dry mouth, medications are to blame. According to the U.S. Surgeon General, there are more than 500 medications (both prescription and over-the-counter) that have this side effect. Antihistamines (for allergies), diuretics (which drain excess fluid), and antidepressants, are high on the list of medications that cause xerostomia. Chemotherapy drugs can also have this effect.
- Radiation Therapy. Radiation of the head and neck can damage salivary glands—sometimes permanently. Radiation to treat cancer in other parts of the body will not cause xerostomia.
- Disease. Some systemic (general body) diseases can cause dry mouth. Sjögren's syndrome, for example, is an autoimmune disease that causes the body to attack its own moisture-producing glands in the eyes and mouth. Other diseases known to cause dry mouth include diabetes, Parkinson's disease, cystic fibrosis and AIDS.
- Nerve Damage. Trauma to the head or neck can damage the nerves involved in the production of saliva.
If you are taking any medication regularly, it's possible that your physician can either suggest a substitute or adjust the dosage to relieve your symptoms of dry mouth. If this is not possible or has already been tried, here are some other things you can do:
- Sip fluids frequently. This is particularly helpful during meals. Make sure what you drink does not contain sugar and isn't acidic, as these will both increase your risk of tooth decay. All sodas, including diet varieties, should be avoided, as they are acidic and attack the tooth surface.
- Chew sugarless gum. This will help stimulate saliva flow if your salivary glands are not damaged. Choose a variety that contains xylitol, a natural sugar substitute that can be protective against tooth decay.
- Avoid drying/irritating foods and beverages. These include toast and crackers, salty and spicy foods, alcohol and caffeinated drinks.
- Don't smoke. This can dry out the mouth and also increase your risk of gum disease.
- Use a humidifier. Running a cool-mist humidifier at night can be soothing.
- Use saliva stimulants/substitutes. There are prescription and over-the-counter products that can either stimulate saliva or act as a substitute oral fluid. We can give you some recommendations.
- Practice good oral hygiene. Brush at least twice a day with a fluoride toothpaste; this will remove bacterial plaque and add minerals to strengthen your teeth. Don't forget to floss.
- Have an exam/cleaning. If you have dry mouth, it's more important than ever to maintain your regular schedule of visits to the dental office. Please be sure to let us know what medications you are taking, particularly if there have been any changes recently. We will do our best to help relieve any dry-mouth symptoms you are experiencing.
