Although tonsil stones are not caused by genetics, several genetic factors may affect the shape and size of the tonsils, which influence the likelihood of these organs harboring debris and forming tonsil stones. As a result, tonsil conditions such as the development tonsil stones may run in families to a moderate degree because of tonsillar structure.

Your palatine tonsils are a pair of oval-shaped structures that are positioned on either side of the back of the throat. These structures are covered by pink mucosa that contains channels and pits that are commonly referred to as the tonsillar crypts. Bits of debris such as food particles, dead cells, mucus, and microorganisms can accumulate in these crypts and begin to decay. If this situation persists, small and pale masses become calcified into hardened tonsil stones.

Recent studies suggest that tonsil stones are also associated with chronic conditions that prompt perpetual postnasal drip, such as respiratory allergies and sinusitis. Many allergies have hereditary associations, and these conditions can influence the development of tonsil stones indirectly by creating the genetic influences of contributing conditions. Additionally, those who suffer from repeated episodes of tonsillar inflammation and tonsillitis are also prone to developing tonsil stones.

Even if you suspect that genetics may give you a predisposition for developing tonsil stones, you can control the effects of this condition by practicing good oral-hygiene habits and by proactively caring for your health. Simple precautions such as using an antimicrobial mouthwash, gargling with warm salt water, and limiting dairy products in your diet can minimize your chances of developing problematic tonsil stones.

If you are experiencing problematic tonsil stones, see your doctor for an oral examination. He or she can suggest at-home remedies and may prescribe an antibiotic to reduce symptoms that may be caused by bacteria, such as bad breath. Alternatively, your doctor may recommend that you see an ear, nose, and throat (ENT) specialist for further evaluation. In more serious cases, your doctor or ENT specialist may suggest the surgical removal of the tonsil stones or of your tonsils themselves.
