How Does Sugar Affect Your Teeth?

Sugar

Do you like to add a little bit of sugar to sweeten up your tea or coffee in the morning? What about the crisp and delicious carbonated beverage you have with your lunch? These days, it’s difficult to avoid sugar. After all, it seems to be everywhere! But how often do you think about what it’s doing to your smile? Read on to learn more from your dentist about how sugar impacts oral health, what you should watch out for in the products you buy, and what sweetener you can use instead.

What Does Sugar Do to Your Teeth?

You know that having sugar too frequently can lead to tooth decay, but how exactly does this happen? It isn’t the sugar that damages your teeth. It is what happens after you eat that sugary food or drink that sweet beverage that causes harm. After eating foods that contain sugar, their molecules combine with the saliva and bacteria present in the mouth leading to plaque buildups on the teeth. If this isn’t cleared away soon, this plaque can dissolve away your enamel and lead to cavities. When it builds up along the gumline, you could develop periodontal disease which is linked to serious complications elsewhere in the body.

Do I Need to Cut Sugar Out of My Diet?

The best thing that you can do is avoid refined or processed sugar. This is the type of harmful sugar that’s found in potato chips, prepackaged snacks, soda, candy, and more. Even though dried fruit, honey, and citrus contain natural sugars, they can still cause harm to your smile if they aren’t eaten in moderation. Some tooth-friendly snacks include cheese, nuts, carrots, celery, and apples. Don’t forget to drink water throughout the day to wash away any lingering bacteria and food debris in your mouth.

Are Any Sugars Safe?

You might have heard about a sweetener called xylitol. It’s a sugar alcohol that doesn’t contain any of the acid producing qualities that sugar does, but still maintains a similar sweetness. It is most commonly found in sugarless gum, candy, mints, and even toothpaste. It inhibits the growth of the type of bacteria that cause cavities and can prevent bacteria from sticking on the teeth. Alike everything else, xylitol should be only consumed in moderation, but it is a great alternative to sugar for your teeth.

By being aware of the effects that sugar can have on your smile, you can make wise decisions to maintain optimal oral health for many years to come!

I've been coming to this practice for years now since moving to the Raleigh area. The office is always clean and organized and the staff have always been friendly and communicative. Also, the TV's mounted to the ceiling are a nice touch! I've been seeing Dr. Laster for several years before our insurance changed causing me to change to Dr. Rensch. Both are so easy to talk to and always made me feel at ease.

From beginning to end 5/5! I thought I was experiencing a dental 911. I submitted an inquiry at 11:30pm and by 8am the next morning, Deidra (front office staff) was already leaving me a message. She was so sweet and patient at 8am lol. After our initial conversation, I informed all follow up dentists “I found my dentist office” but thank you so much! Today I was welcomed with the same energy from Diedre to Britany then finally Dr.Wrench. The music playing throughout the office was fantastic; ie music selection and volume. The TV’s on the ceiling and wall made my procedure so painless and enjoyable! I watched an entire Christmas movie lol! Dr. Wrench (apologies for spelling) made my teeth absolutely perfect! I left telling my friends and family I have a million dollar smile! 😊 I can tell he wanted them perfect and he did! Thank you all so much for being amazing! Sincerely, Your next patient.

Dr. Laster and Dr. Rensch go above and beyond for their patients. I have seen both for various treatments and I always feel comfortable and heard. They take time to listen and to talk with you. They explain your options and work with you to develop the best plan for your care. They are always upbeat and positive and you can tell they truly love what they do. The front desk staff is exceptional as well. Deidre is so caring and very sweet. She’s efficient, understanding and conscientious of your time. I highly recommend.

Connections Dentistry was great! The staff is so friendly and truly cares about their patients. My appointment was quick, and honestly the best dental experience I’ve had. They are great about offering helpful solutions without making you feel like you are being reprimanded… which was the reason I was putting off the dentist. 100% recommend!
