New research suggests that some medicines could cause decay to form in teeth that are otherwise healthy and well cared for; studies from Australia and Scandinavia have suggested that asthma medication can increase the risk of cavities because of the slightly acidic content. If used properly, the inhaler and the drug it contains should not come into direct contact with the teeth, which could reduce the damage done to the enamel.
However, asthma medication is also available in a powered form, which could leave a residue on the teeth that would contribute to decay over time. Dr Mervyn Druian, of the London Centre for Cosmetic Dentistry explains that patients should be on the lookout for early symptoms to stop the condition in its tracks, saying ‘changes begin with brown areas, no bigger than a pinprick, on the inside of the teeth. Teeth begin to feel rougher if you run your tongue along them, and more sensitive. Without meticulous dental hygiene these can develop into cavities.’
Experts suggest rinsing the mouth out after an inhaler or medication for asthma has been used, and maintain a high standard of dental hygiene – including brushing and flossing. It is also recommended that sufferers visit the hygienist three times a year; these visits will help protect against decay because a fluoride paste will be applied to strengthen the teeth and other products to encourage the flow of saliva to prevent cavities from developing.
