there are several prescribtion and over-the-counter medications that cause dry mouth as a side effect. saliva is our natural defense against decay. it almost acts like an cleansing agent for our teeth and gums. when the mouth drys up, bacteria grows at a much faster rate putting your teeth at risk for decay and your gums at risk for periodontal disease. there are over-the-counter products such as biotene that help replace enzymes that your saliva has back into the mouth. rinsing with such products a couple times a day along with hydrating your mouth with plain water can help prevent dental decay and gum disease. for more information please visit our website at serenefamilydentistry.com or stop in to our ladera ranch office to visit with our doctor.
