Best remedy for a cavity.. Is baking soda good for it?

you can try baking soda however i dont recomment overusing it and using it over long periods of time.

There is no remedy for a cavity, they do not fix themselves. You can slow down there expansion by brushing you teeth often to keep the population of bacteria living in the cavity down.

Caries are cause by bacteria that release chemicals that eat away the enamel of the tooth.

Plaque is a sticky film of bacteria that constantly forms on your teeth. When you eat or drink foods or beverages containing sugars, the bacteria in plaque produce acids that attack tooth enamel. The stickiness of the plaque keeps these acids in contact with your teeth, and over time the enamel can break down forming a cavity.

So brush your teeth and eat less sugar, this will slow down the expansion in size of the cavity but it will not "heal" them. Some tooth pastes have chemicals in them that make the enamel harder and more resistant to the acids.

A dentist is the only solution.

But feel free to try home remedies...assuming you like pain

A filling from the dentist would help... you really need to consider getting this fixed. It's dangerous to walk around with infected teeth.

No. Brush your teeth.

The only thing that will help is going to the dentist and getting a filling.
Your teeth cannot heal themselves. You need a filling.

I have no idea....maybe seek advice from a dentist not an unprofessional like myself

Yes best remedy for a cavity.. Is baking soda good for it.
