All four of my first molars are infected, two have mercury fillings. i want to get all the four teeth extracted and the metal removed. which modern dentures are best for me?

Need exam: Firstly, the silver fillings are not the cause of your infections. Secondly, are the teeth restorable? Thirdly, what is the condition of the remaining teeth? Lots of questions, all to be answered by your local dentist. Please call for an appointment.

Consult: No dentures or even implant supported prostheses are 'best' for you. Healthy natural teeth are best. What is the next best for you can only be determined after a complete set of x-rays, a thorough one-on-one clinical exam and a consult with the best general dentist or prosthodontist you can find. Make sure you fully understand your options prior to making any decisions. Get a 2nd opinion as well.

Implants: Assuming your teeth cannot be saved which is your best option, then dental implants are the best means of replacing your missing teeth.

Dental implants: If there is enough bone remaining then 4 single implants placed in those locations, with 4 single crowns , is the best long term treatment. See a prosthodontist for guidance, treatment and referrals before having the teeth removed.
