What Does a Cavity Look Like? How to Spot Tooth Decay Early

Cavities are one of the most common dental issues we treat at MDRN MUSE in Chattanooga. They can sneak up on you, often without any pain at first, which is why early detection is key. If you have ever wondered what a cavity actually looks like or how to tell if you might have one, this guide will walk you through the basics.
What Exactly Is a Cavity?
A cavity is a small hole in your tooth caused by decay. It starts when bacteria in your mouth feed on sugars from food and drink, producing acids that wear down your tooth enamel. Over time, if not treated, this decay can move deeper into the tooth, affecting the dentin and even the nerve.
Cavities are progressive, which means they only get worse if ignored. That is why catching them early makes treatment simpler and protects more of your natural tooth.
What Does a Cavity Look Like?
Cavities can appear differently depending on their stage and location. Some common visual signs include:
● White spots – Often the earliest signs of enamel breakdown. You may see chalky, pale areas on the surface of your tooth.
● Brown or black spots – As decay progresses, it often turns darker. These may be tiny or cover a larger portion of the tooth.
● Visible holes or pits – When decay has gone deeper, you may be able to see or feel a small hole.
● Staining between teeth – Sometimes cavities form in places you cannot see clearly, like between teeth. These often show up on X-rays first.
Even if your teeth look fine, cavities can still be present—especially in hard-to-see areas. That is why regular dental checkups at MDRN MUSE are so important.
What Does a Cavity Feel Like?
Early cavities usually do not cause pain. But as they grow, you might notice:
● Tooth sensitivity when eating or drinking something sweet, cold, or hot
● A dull ache that comes and goes
● Pain when biting down
● A rough texture when you run your tongue across a tooth
If you notice any of these symptoms, it is a good idea to schedule an appointment. At MDRN MUSE, we use advanced technology to diagnose cavities before they become painful problems.
Why Early Detection Matters
The earlier we find a cavity, the easier it is to treat. Small cavities can often be repaired with a simple, tooth-colored filling. Left untreated, they can lead to:
● Infections and abscesses
● Tooth fractures
● Root canals or extractions
● Costly and more complex dental work
By coming in for regular checkups, we can catch cavities when they are still easy to fix—and often before you even know they are there.
How We Detect Cavities at MDRN MUSE
At MDRN MUSE, we blend a modern approach with meticulous care. During your exam, Dr. Youngblood will:
● Visually examine each tooth using magnification and lighting
● Use digital X-rays to spot decay between teeth or below the surface
● Gently check for soft spots with a specialized dental instrument
We prioritize conservative, preventative care, meaning our goal is always to catch issues early and preserve your natural teeth as much as possible.
How to Prevent Cavities
Good oral hygiene is your best defense against cavities. Here are some quick tips:
● Brush twice daily with fluoride toothpaste
● Floss every day to clean between teeth
● Limit sugary snacks and drinks
● Drink water often, especially after eating
● Visit MDRN MUSE every 6 months for cleanings and exams
We also offer fluoride treatments and dental sealants for extra protection, especially for children and teens who are more cavity-prone.
