I am having problems with my permanent retainer on my lower 4 front teeth I have really bad build up of tater on the back but now 2 of my teeth in the front are going black between them and along the gums. I would like to know if this can be handled with a cleaning or if it s more serious?
Thanks for your query, I have gone through your query. The black discoloration can be because of the stains secondary to coffee or tea or smoke. The other possible cause is decay of the teeth. Consult an oral physician and get it evaluated. If it is stains then cleaning of the teeth will solve the problem. If it is decayed teeth, then it has to be restored with tooth color restorative material. I hope my answer will help you, take care.
