Toothache - Why Won't My Tooth Pain Go Away?

Technology in dentistry now offers attractive options in dental fillings for cavity restorations in dental care. Called composites, these new tooth-colored dental fillings are excellent choices for front teeth and other repairs that might be visible. Composites duplicate the natural appearance of a tooth in restoring decayed teeth or repairing a defect and giving you a more attractive mouth.

What Dental Care Material Is Used in the Composite Filling?

Dental fillings composites are made from a mixture of microscopic plastic and ceramic resin particles. Another type of tooth-colored dental fillings used in dental care are called a resin ionomer, which releases fluoride useful for preventing tooth decay.

Besides Their Cosmetic Value, What Other Benefits Do Composites Provide in dental care

The bonding process used in restoration provides strength to the tooth, making it more structurally sound. It also seals the tooth, decreasing the chance of sensitivity to hot and cold. Some composites made with materials releasing fluoride are ideal for treating root decay, a condition when gums recede, exposing tooth roots to more cavity-causing plaque. These fluoride-releasing materials also are useful dental fillings for decayed baby teeth.

What Is the Process for Dental Care Treatment?

Following removal of the decayed area, a mild acid solution is used to prepare the tooth's surface for bonding and dental fillings. A bonding agent is then brushed over the surface. Several layers of the composite are applied during the next dental care process. For a natural appearance, the dentist matches the color of the dental fillings composite to the tooth.

Then, it is chemically hardened or cured with a special light and finally polished for a natural-looking finishing touch.

How Durable Are these Dental Fillings?

In a five-year clinical study of dental care, some of the resin materials demonstrated 100% effectiveness for adhesion and retention. Like other types of dental fillings, they may require periodic replacement. While the material is very durable, they may not perform quite as long as silver fillings or amalgams for their resistance to the rigors of grinding and chewing.

Scheduling dental care on a regular basis is an important part of good oral hygiene. Your dentist will check your fillings each time to ensure their performance.

Your Dental Visit

When you first visit a new dentist, part of your initial exam is an assessment of your "bite" - the way teeth meet as the jaws close. Later, after a filling or placement of a dental crown, your bite will be tested again to be sure the tooth restoration fits well with other teeth. Nearly all dental patients have "been there." And there's good reason for this attention to bite.

Chewing, tooth wear and joint function all depend on the balanced opposition of teeth in each jaw. Any disruption of a good bite, either by broken, loose, or lost teeth, is trouble in need of repair. In the worst-case scenario - the jaws themselves present skeletal problems - orthodontic treatment is considered. However, most malocclusions (bad bites) are treatable right in your dentist's office.

Your dentist will first locate ill-fitting teeth by routine bite analysis. You will bite down on a sheet of special paper that marks teeth with uneven wear. If this doesn't tell your dentist enough, he or she may take impressions, from which study models are built. This gives your dentist a very visual demonstration of what's wrong.

High points in enamel that interfere with normal contact may be filed away. Eroded fillings call for replacements. Lost teeth need a bridge or dental implants to prevent opposing teeth from overgrowth. There are any number of solutions to a bad bite, all important to your dental health.

Anytime you notice a change in your chewing habits, or feel more pressure than usual on a solitary tooth, bring it to your dentist's attention. You'll notice the abnormality, maybe before your dentist detects it. Since you'll be working together, tell your dentist your suspicions and, if it's broken, it can be fixed.
