A tooth filling is a dental restoration treatment used to repair a decayed, cracked or damaged tooth. It involves removing the affected portion of the tooth and filling the hole with a dental material to restore its structure, function and integrity.

A tooth gap filling, or dental bonding, is a cosmetic procedure to close spaces or gaps between teeth. A tooth-colored composite resin is applied to the affected area, which is then shaped and polished to blend in with your surrounding teeth. This is a good option if you wish to improve the appearance of your smile by addressing gaps, irregular spacing or minor cosmetic imperfections.

If you’ve had nitrous oxide, you can return to normal activities once you leave the dental office. However, if you’ve had oral or intravenous sedatives, you’ll need to wait at least one full day before returning to work or school. Some people may need longer. Your dentist can tell you what to expect in your situation.

Typically, a straightforward filling procedure takes about 30 to 60 minutes from start to finish.​ Your dental filling procedure could be different depending on the size and location of your cavity, the type of filling material used and the dentist’s technique. If you have multiple cavities or need more complex treatment, the procedure may take longer.
 
Here’s what you can expect at your dental filling appointment.
 
First, the dentist numbs the area around the tooth.
Using a local anesthetic, your dentist will numb the affected area to make sure you’re comfortable during the procedure. Then, using a dental drill or other instruments, your dentist will remove the decayed part of the tooth, clean out the cavity by shaping it and ensuring it’s free of any debris.​
 
Next, the filling material is applied to the prepared cavity.
The type of filling material can vary—common options include composite resin, amalgam, gold or porcelain. Composite resin is popular because it can be color-matched to your natural tooth shade. Amalgam, once the filling of choice, is a less commonly used material but still sometimes preferred for back teeth where chewing forces are stronger.
 
Lastly, your dentist will shape the dental filling and polish it.
Your dentist will make sure your dental filling fits well with your bite and looks natural. Afterward, you may experience some numbness in the area, which typically wears off within a few hours.

After getting a filling, it’s common to experience some degree of sensitivity or discomfort in the treated tooth. This may happen if you have initial sensitivity, a high filling that requires adjustment, irritation of the tooth’s nerve during the procedure, or, in rare cases, underlying issues like infection or an allergic reaction to the filling material.
 
If you experience persistent or severe pain after a dental filling, you should contact your dentist immediately for a thorough evaluation and treatment. ​

Generally, tooth-colored composite fillings can last five to 10 years, while silver amalgam fillings may last 10 to 15 years. ​The lifespan of tooth fillings depends on factors like the filling material used, your oral hygiene, diet and the location of your filling.
 
However, with proper care and regular dental check-ups, your fillings can often last longer. Follow your Austin Emergency Dental dentist’s advice on maintaining and monitoring your fillings for the best results..

Typically, immediate sensitivity to hot or cold foods and drinks may occur right after the procedure, but this usually diminishes within a few days as the tooth adjusts to the new filling. Mild soreness or discomfort in the tooth and surrounding gums can also be expected for a short period. Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage this discomfort.​
 
If the pain persists beyond a week, continues to worsen, becomes more sensitive to hot liquids or foods or if you notice other concerning symptoms such as swelling or throbbing pain, it may indicate a need for further evaluation by your dentist. Persistent discomfort could suggest issues such as an uneven bite caused by a high filling. In such cases, contacting your Austin Emergency Dental dentist for a follow-up appointment is recommended to address any underlying problems and ensure your comfort and oral health are properly managed.

Yes, you can eat after getting a filling, but it’s recommended to wait until the numbness from the anesthesia wears off. Typically, this takes a couple of hours. During this time, it’s best to avoid eating to prevent accidentally biting your tongue, cheeks or lips due to numbness. Once the anesthesia wears off and you regain normal sensation in your mouth, you can resume eating.​
 
It’s also advisable to start with soft foods and avoid chewing on the side where the filling was placed if you experience any discomfort or sensitivity. Hot and cold foods or drinks might initially cause sensitivity, so consuming foods at a moderate temperature can help minimize discomfort. If you feel any unusual pain, sensitivity or have difficulty chewing after eating, it’s a good idea to contact your dentist for further guidance.​
