Even with regular and proper brushing technique, when the color of teeth darkens due to internal or external factors, the first step to follow should be to visit your dentist for an examination.
After the cause of discoloration is diagnosed, the most protective treatment for achieving lighter colored teeth is teeth whitening.
For discolorations that are spread throughout the teeth, a lighter tooth color can be achieved after an office-type whitening procedure performed with appropriate techniques.
The treatment of brown or gray discoloration of teeth that have undergone root canal treatment or have suffered damage to the pulp tissue is possible with a procedure called internal whitening. An medication placed under the filling in the affected tooth is left to take effect for a few days, and then the medication is removed and the permanent filling of the tooth is done. It is a repeatable procedure until the desired level is reached.
