Dental fillings
What Happens During a Filling?
Dental fillings are one of the most common procedures performed in a dental office—second only to routine cleanings. Tooth decay remains one of the most prevalent chronic conditions in both children and adults. In fact, according to the CDC, tooth or root decay affects 9 out of 10 adults over the age of 20 and is widespread among children ages 6–19.
Unlike other parts of the body, teeth cannot heal themselves once damaged. That’s why it’s so important to treat cavities early, before they lead to more serious issues such as root canals, crowns, or even tooth loss. Left untreated, cavities can also contribute to shifting teeth and bite misalignment.
When a tooth requires a filling, the decayed portion is carefully removed and the area is thoroughly cleaned. Once the tooth is prepped, a specialized material is used to restore the structure and function of the tooth.
There are a few types of materials used for fillings, with the most common being:
- Silver Amalgam: Durable and cost-effective, often used in back teeth.
- Composite Resin: Tooth-colored and natural-looking, making it ideal for visible areas.
Composite fillings are custom-shaded to match your surrounding teeth, providing a seamless and aesthetically pleasing finish.
Preventing Tooth Decay
The best way to avoid fillings is to prevent decay before it starts. Follow these simple steps:
- Brush your teeth twice daily with fluoride toothpaste
- Floss or use interdental cleaners to clean between teeth
- Eat a balanced diet and limit sugary snacks
- Schedule regular cleanings and checkups
- Ask about fluoride treatments and protective dental sealants, especially for children
Frequently Asked Questions (FAQ)
How do I know if I need a filling?
Common signs include tooth sensitivity, visible holes, dark spots, or discomfort when chewing. A dental exam with X-rays will confirm whether a filling is needed.
Is getting a filling painful?
Most fillings are performed under local anesthesia, making the procedure quick and comfortable.
How long do dental fillings last?
Composite fillings typically last 5–10 years, while silver amalgam can last longer. Lifespan depends on oral habits, the material used, and the location of the filling.
Can I eat after getting a filling?
If a composite resin is used, you can usually eat right away. If an amalgam filling is placed, you may be advised to wait a few hours.
How can I prevent cavities in the future?
Practice good oral hygiene, eat a balanced diet, avoid frequent snacking, and maintain your dental visits every six months.
