Cavity Fillings and Sealants

How do cavity fillings work?

Cavity fillings work by removing the decayed portion of the tooth and filling the area with a durable material to restore its shape and function. The process begins with the dentist numbing the area around the affected tooth to ensure comfort. Next, the decayed material is carefully removed, and the cavity is cleaned. A tooth-colored composite resin is then applied in layers, hardened with a special light, and shaped to fit the tooth’s natural contours. Finally, the filling is polished to ensure a smooth and natural appearance, effectively restoring the tooth’s health and functionality.

What types of filling materials are available?

At Old Betsy Dental, we offer two types of filling materials to suit your dental needs:

1. Composite Resin: Tooth-colored and durable composite fillings blend seamlessly with your natural teeth, making them ideal for visible areas.
2. Amalgam: Made from a mixture of metals, amalgam fillings are strong and long-lasting, making them suitable for back teeth where chewing pressure is greatest.

Your dentist will help you choose the best filling material based on the location and extent of the cavity, as well as your personal preferences.

Should I have tooth sensitivity after a filling?

Yes, it is normal to experience some tooth sensitivity after a filling. This sensitivity can occur when the tooth is exposed to hot, cold, sweet, or acidic foods and drinks. The sensitivity is usually temporary and should subside within a few days to a couple of weeks as the tooth adjusts to the filling. If the sensitivity persists or becomes severe, it is important to contact your dentist for an evaluation to ensure there are no underlying issues that need to be addressed.

Minimize Tooth Sensitivity

You can reduce the sensitivity in your teeth and gums by:

• Taking an anti-inflammatory drug, like Advil or Motrin
• Temporarily avoiding hot, cold, or acidic foods and beverages such as fruit, wine, and yogurt
• Brush and floss more gently
• Use a desensitizing toothpaste like Sensodyne or Colgate Sensitive

How long does a dental sealant last?

A dental sealant can last several years, typically ranging from 5 to 10 years, depending on factors such as your oral hygiene practices and chewing habits. Regular dental check-ups are essential to monitor the condition of the sealants and ensure they remain intact. Your dentist can reapply sealants if necessary to maintain their protective benefits and help prevent cavities.

Who qualifies for dental sealants?

Dental sealants are ideal for children and teenagers, as they are most effective when applied to newly erupted permanent molars and premolars. However, adults who do not have cavities or fillings in their molars can also benefit from sealants. Sealants are particularly beneficial for individuals with deep grooves and fissures in their teeth, as these areas are more susceptible to decay. Your dentist can evaluate your teeth and determine if you or your child are good candidates for dental sealants.
