There are spot treatments which general dentists do not have access to - which you must go to a periodontist for. My back molar had some bad sensitivity - and i could not risk loosing it before a major dental surgery - so i had this treatment done. These spot treatments (topical) last for 4-6 months. Going to a perio will cost you though (obviously)
