Humans have always had cavities, and throughout history they’ve sought out better and better ways to treat them. That’s why today’s dentists have so many tried and true materials to choose from when it comes to placing a filling. If you have a cavity, your dentist may use metal, like gold or amalgam, but most dentists also offer more natural-looking alternatives, such as composite fillings.

The composite resin used in this type of filling is made from a blend of quartz, glass and plastic resin, and can be used for both front and back teeth. Because they mimic natural tooth color, they are often preferred by patients who dislike the look of metal fillings.

Reasons for Resin

While every type of filling has its own advantages and disadvantages, dentists who choose composite fillings generally do so because they:

- Are typically smaller than other fillings and require less tooth structure to be removed
- Provide a more aesthetic look
- Bond to the tooth for additional support and tooth strength
- May cause less sensitivity to heat and cold than metal fillings
- Allow dental care for patients with metal allergies

Talk to your dentist about what type of fillings he or she recommends. Although composite resin is a popular choice, it’s not for everyone. The material is slightly more expensive than metal fillings and can require more chair time to place. In addition, composite fillings may not last quite as long as other materials and, just like your natural teeth, can become stained or yellow over time. Let your dentist know about your goals, budget and preferences to help choose the right method for your dental care.

Have Your Fill

During your appointment, your dentist will numb the tooth and surrounding area with a local anesthetic and use a drill, laser or air abrasion tool to remove the decayed material. The composite resin is applied in layers, with a special light being used to harden each layer before the next is placed, until the entire cavity is filled. Finally, your dentist will make sure the shape of your filling does not interfere with your bite and finish off by polishing it for a natural-looking, white appearance.

Aftercare

It is normal to experience some sensitivity to extreme temperatures immediately after receiving your filling. If needed, your dentist can suggest a desensitizing toothpaste. Most patients will not need any pain relievers and can eat and chew normally as soon as the numbness wears off.

The most important thing to remember is that while composite fillings are an effective way to treat your cavities, your dentist would much prefer that you prevent them all together. After receiving your filling, it’s usually a good idea to reevaluate your oral hygiene regimen to make sure you’re brushing and flossing properly -- because even the most natural looking filling can’t compare with beautiful, healthy teeth.
