Professional cleaning involves the removal of stains, plaque and tartar that have accumulated on your teeth, tooth scaling to remove plaque below the gum line, and tooth polishing
The professional cleaning of teeth is sometimes referred to as prophylaxis which means “to prevent beforehand” – in this case it helps prevent gum (periodontal) disease.
Even on regular brushing or flossing ,there is a chance of tartar formation in areas which are difficult to reach.it is important to remove this periodically to maintain proper oral hygiene.
Tartar formation tend to accumulate below the gum line.this is the main reason for bad odor and gum disease. Sensitivity around teeth,food impaction,gum recession(reduced gum height),bleeding while brushing or red inflamed gums-all these indicates that you have gum disease or periodontal disease.
According to severity of your condition,your dentist will recommend for a simple scaling(non surgical) or surgery to eliminate the gum disease.you can avoid surgery by using LANAP(laser assisted new attachment procedure)as an alternative.
