What Causes Cavities And How to Prevent Them
Cavities are one of the most common dental issues we treat in Topsham ME and Biddeford ME—and they can sneak up on anyone. At Gentle Dental, we understand how untreated tooth decay can lead to pain, infection, and bigger health problems down the road. That’s why we’re focused on helping you recognize, prevent, and treat cavities early—before they have a chance to do lasting damage.
Why Do Cavities Form?
Let’s break it down: Every time you eat or drink, especially foods high in sugars or starches, bacteria in your mouth get to work. These bacteria produce acids that attack the outer layer of your teeth—your enamel. Over time, that constant acid exposure can create tiny holes in your teeth. That’s what we call a cavity.
Your saliva helps by neutralizing acids and repairing early damage, but if the balance tips and acid wins, decay begins to spread.
Signs You Might Have a Cavity
Not every cavity comes with flashing lights and sirens. Some sneak in quietly. Here are a few symptoms to watch for:
- Tooth Sensitivity – A twinge when sipping hot coffee or biting into ice cream?
- Visible Pits or Dark Spots – Little marks or holes can signal decay.
- Persistent Toothache – Ongoing pain, especially when chewing, might mean the cavity has reached a deeper layer.
- Bad Breath or Unpleasant Taste – Bacteria from decaying teeth can cause lingering odor or taste.
If any of these sound familiar, it’s time to let your dentist take a look.
Who’s Most at Risk for Cavities?
Tooth decay doesn’t discriminate—but certain habits and conditions raise your risk:
- Sugary & Acidic Diets – Soda, juice, candy... we all indulge sometimes, but too much wears down enamel fast.
- Dry Mouth – Saliva is your mouth’s natural defense. If you’re not producing enough, decay gets a head start.
- Inconsistent Oral Hygiene – Skipping brushing or flossing gives bacteria the freedom to thrive.
- Medical Conditions – Diabetes and certain medications can increase cavity risk, too.
At Gentle Dental, we take time to understand your lifestyle and help you build healthy habits that stick.
Cavities at Every Age: What to Know
Kids and Teens
Between sugary snacks and learning proper brushing techniques, kids are often cavity-prone. Early decay can lead to discomfort, missed school, and even long-term dental issues. Regular visits help catch problems early and keep little smiles healthy.Adults
For adults, stress, poor dietary choices, or smoking can contribute to decay. Even if you’ve had great teeth for years, that can change quickly. Preventive care and early intervention are key.Seniors
As we age, receding gums and dry mouth become more common, increasing the risk of root decay. Routine check-ups help seniors maintain strong, functional teeth well into their later years.
How to Prevent Cavities Like a Pro
Prevention is powerful—and often easier than you think. Here’s what we recommend:
- Brush Twice Daily – Use a soft-bristled toothbrush and fluoride toothpaste.
- Floss Every Day – Get between teeth where your brush can’t reach.
- Rinse with Fluoride – Consider adding a fluoride mouthwash to strengthen enamel.
- Eat Smart – Choose water, whole foods, and snacks low in sugar and acids.
- Visit Us Regularly – Professional cleanings and check-ups every six months help catch decay early.
Our team is here to give you the tools and guidance to protect your smile for life.
What If You Already Have a Cavity?
The good news? Cavities are treatable—and the sooner we catch them, the simpler the fix.
- Fluoride Treatments
For early-stage decay, fluoride can help remineralize the enamel and stop damage in its tracks. - Dental Fillings
If decay has created a cavity, we gently remove it and fill the space with a durable, natural-looking material that blends right in. - Root Canal Therapy
When decay reaches the inner pulp of the tooth, a root canal may be necessary to remove the infection and save your tooth. - Tooth Extraction
If a tooth is too damaged to repair, we’ll discuss safe, comfortable extraction and explore replacement options like bridges or implants to restore your smile.
