I have weak teeth and don't know what to do. help?

See a dentist: Make an appointment with a dentist to have your situation evaluated. The dentist will be able to formulate a treatment plan and present the options you have to fix your teeth.

Agreed: I would agree with dr. Hertzel. There are a variety of treatment options that combine home-use products such as prescription strength fluorides and office treatments such as crowns and fillings that your dentist can recommend based on your specific situation. You will need to approach the issue from two directions. 1: fixing any existing decay and 2: preventing future decay.

Quality matters ...: I recommend you seek out a dentist who uses the finest, biologically compatible, strengthening white dental materials available. Also, a dentist who works in microscopic surgical loupes & makes sure there is a microscopic seal. This can help you to retain dental crowns & fillings. Weak teeth are challenging & require exceptional quality materials & workmanship. Put money away yearly for your teeth.
