Tooth Decay – What Is It and What Causes It?

Tooth decay is a common problem that can (seemingly) come out of nowhere. Alas, it’s usually a situation that’s been in the works for a long time, but many people who don’t get regular dental cleanings can’t see it coming.

Rest assured that our Lasalle dental facility fields this question frequently, and our skilled team of professionals is here to help. No matter the state of your mouth, we can help make oral health a reality for you and your family.

Here are a few things you need to know about dental decay:

1. Bacteria Causes Tooth Decay

Your mouth naturally produces acid throughout the day, particularly when you eat or drink. Eventually, leftover food and oral acids produce bacteria. When bacteria and acids are left to their own devices, they begin to eat away at the enamel on your teeth.

Enamel is the protective layer of your teeth, which prevent the blood vessels and nerves within your teeth from being harmed. If acids and bacteria eat away at this shield, you could wind up in pain or discomfort, as these elements become exposed.

2. Sugary Foods Invite Tooth Decay

Sugar loves oral bacteria. It makes best friends with these tiny bits, coating every inch of enamel with decay-inviting mechanisms.

Remember, sugar is found in everything from soft drinks to candy to tempting desserts.

To avoid this enamel destruction, be sure to brush your teeth after every meal; this will help eliminate the acids your mouth produces while ensuring your teeth are free and clear of sugary substances.

3. Everyday Foods Offer Decay-in-Waiting

Sure, you already know that sugary items such as candy and soda can eat away at your enamel, but are you aware of the other everyday foods that can wreak havoc on your teeth?

Bread and fish, for example, contain a high amount of enamel-reducing acids. Other items you might not think about include the glass of wine you have with your dinner, the soda you sip on at work, and the orange juice you drink before you head to the office.

Each of these everyday foods contains acids that can soften your enamel, making your teeth susceptible to tooth decay.

4. Grinding Your Teeth Can Cause Decay

Excessive stress and unusual sleeping patterns can cause a person to grind their teeth. Over time, this action can wear down the outer layer of teeth, providing an easy way for tooth decay to find its way into a person’s life.

At our Lasalle dental clinic, we see this regularly. Thankfully, a properly fitted bite guard can alleviate grinding problems and protect your teeth from nighttime stresses.
