Hello I have a tooth cavity which is the best...

Treatment of teeth cavities:
First of all, tooth cavity is a common problem that a lot of people are suffering from and it's recommended to visit a dentist to assess your condition and treat you accordingly. Regular checkups can find cavities and other dental issues before they lead to more-serious problems. The sooner you seek care, the better your chances of reversing the earliest stages of tooth decay and stopping it from getting worse. If a cavity is treated before it starts causing pain, you probably won't need a lot of treatment. Treatment of cavities depends on how serious they are and your situation.
Treatment options include:
- Fluoride treatments which help restore your tooth's enamel and can sometimes reverse a cavity in the very early stages. Fluoride treatments may be liquid, gel, foam or varnish that's brushed onto your teeth or placed in a small tray that fits over your teeth.
- Fillings (restorations) are the main treatment option which are made of various materials, such as tooth-colored composite resin or porcelain, or dental amalgam that is a mixture of several materials.
- Crowns. If you have a lot of decay or weakened teeth, you may need a crown.
- Root canals to repair and save a badly damaged or infected tooth instead of removing it.
- Tooth extractions. Some teeth become so seriously decayed that they can't be restored and must be removed.
