How to Choose the Best Toothbrush For Your Needs
May 15, 20257 Reasons Why You Shouldn’t Ignore Bleeding Gums
July 14, 2025Nobody likes hearing the words, “You have a cavity!” But cavities are common, and they can happen to anyone, even if you think you take pretty good care of your teeth. Knowing the early indicators of cavities can help you catch them before they cause bigger problems, like severe tooth pain or infections. Here are the top five signs of cavities to watch out for, and what you can do if you notice any of them.
1. Tooth Pain or Sensitivity
Ever had a sharp pain hit your tooth when you were enjoying an ice cream cone or sipping hot coffee? If your teeth hurt when exposed to hot or cold foods and drinks, it might be a sign of cavities. Tooth pain or increased sensitivity often means that the protective layer (your tooth enamel) is damaged, allowing foods and temperatures to affect the nerves inside your tooth.
2. Visible Holes or Pits in Your Teeth
One of the clearest signs of cavities is seeing holes or pits on the surface of your teeth. Cavities start small and gradually become larger and deeper if untreated. If you notice small holes or dark areas when you’re brushing your teeth, this is a clear signal that decay has already set in. Don’t ignore this! It’s important to address it sooner rather than later.
3. Brown, Black, or White Spots
Have you seen brown, black, or even chalky white spots on your teeth? These discoloured spots often indicate the early stages of tooth decay. Brown or black spots are usually more advanced, meaning the cavity is well on its way. White spots are typically the very first sign of enamel weakening, so catching these early can help prevent further damage.
4. Bad Breath or a Bad Taste in Your Mouth
Persistent bad breath or an unpleasant taste in your mouth, even after brushing your teeth, can signal that something is wrong. Cavities form when bacteria in your mouth feed on leftover sugars from foods and drinks that cling to your teeth. This bacterial activity produces acids that cause decay and a bad smell. Good oral hygiene can help, but if bad breath sticks around, it might be a cavity causing trouble.
5. Pain When Eating or Drinking
If chewing or drinking causes sharp or persistent pain, it’s a strong indication that you might have a cavity. Pain during meals occurs because food and drink irritate the sensitive areas exposed by tooth decay. Even slight discomfort can be an early warning, so don’t brush it off, this is your tooth’s way of telling you it needs some professional help!
6. Toothache or Pressure
Experiencing an ongoing toothache or feeling constant pressure in your teeth or jaw can also signal the presence of cavities. This persistent discomfort occurs when decay has reached deeper layers of your tooth and is beginning to affect nerves and tissues. If you’re dealing with a consistent toothache or uncomfortable pressure, it’s time to get checked out by your dentist.
When to Visit a Dentist
You should visit your dentist as soon as possible if you experience any of these signs of cavities. Your dentist can check your oral health thoroughly and identify any problems early on, preventing cavities from becoming more severe. Regular dental check-ups are essential to maintain good oral hygiene and prevent tooth decay. Dentists can also provide helpful advice tailored to your specific needs, like managing dry mouth (which can increase your risk for cavities) or recommending changes in your brushing and flossing routine.
Ignoring these symptoms and delaying treatment can lead to more serious issues, including severe pain, infections, and even tooth loss. It’s always better (and less expensive!) to catch cavities early.
Final Thoughts
Cavities might be common, but they don’t have to ruin your smile. Watch out for these top signs of cavities, like tooth sensitivity, visible holes, discoloured spots, persistent bad breath, and pain while eating or drinking—and take action quickly if you notice them. Keeping up with regular brushing and flossing, along with routine visits to your dentist, can help you stay ahead of cavities and keep your oral health in great shape. Remember, catching cavities early not only saves you discomfort but also protects your teeth for years to come!
