In recent months, we have seen an increase of tooth decay with our patients, especially with the teenagers and the elderly. For teenagers, it's the increase of drink power drinks and soda which decrease the pH in the mouth making it more acidic. For elderly, it's the increase medications they are taking. Most medications decrease salivary flow. As we age, our saliva gets thicker which can means increasing the acidic in the mouth. An increase acidic or decrease of pH can promote an optimal environment for the Streptococcus Mutan and/or Lacto-bacilli bacteria to cause cavity in teeth.
Here are a few things one can do to reduce this risk. First, decrease snacking and sugar intake. Any food debris left on teeth will eventually break down to a weak acid by the bacteria that can slowly dissolve enamel. Processed drinks such as sodas, “thirst quenching drinks” and even juices contain high amount of sugar and are also highly acidic, which can also be detrimental to teeth. Secondly, if you are taking medications regularly or drink caffeinated beverages daily, you are experiencing dry mouth whether you realize it or not. With less saliva to fight against cavity, you are more prone to getting tooth decay as well. Increasing your water intake to 6-8 glasses daily can help to re-hydrate your salivary glands and dilute the acid in your mouth. Since most tooth decays are between the teeth and along the gum line, practicing better oral hygiene especially flossing daily will help you tremendously. Topical fluoride treatments such as mouth rinse and professional fluoride varnish can help to reduce cavity. The fluoride treatments are far less costly than having a cavity filled. Finally, use chewing gums that contain Xylitol, an antibacterial agent, as the only sugar substitute. For more information, please let us know and we will be happy to assist you.
