What Are the Signs of a Cavity Forming?

October 7, 2021

No one wants to go to their bi-annual dentist appointment to find out they have a cavity. If you keep up great dental habits and visit the dentist often enough, you’ll most likely be able to prevent cavities. However, even with great habits, they can sometimes still occur. How do you know if you have one starting to form at home that should be checked out? Below are some common signs you may have one beginning to form.



Extra Tooth Sensitivity

While sensitivity to hot and cold temperatures may be something you deal with on a daily basis, it could also be a sign of a cavity if you don’t normally experience it. As your tooth decays from a cavity, the dentin in your tooth becomes exposed, which is ultra-sensitive material. You may notice that they feel more sensitive than usual, especially if just one or two specific teeth are affected or experience a surge of pain.


Pain

One of the most common signs of a cavity is pain in a tooth. It may be harder to do certain tasks such as brushing, flossing, biting down, or even breathing in cold air. This pain is due to the dentin and inner nerve of the tooth being exposed when it shouldn’t be. You should never be experiencing daily pain in your teeth or mouth, so even if it’s not a cavity, it might be a sign of something else.


Bleeding or Swollen Gums

It’s possible for a cavity to be near the gumline, in which case the gums will be impacted. The decay and infection around the tooth can affect the soft tissue, which then causes swollen gums. They may not be impacted until you brush, in which case you may notice bleeding that usually doesn’t occur.


Even if the swollen and/or bleeding gums aren’t due to a cavity, there may be another issue occurring such as gingivitis, so it’s best to consult with a dentist either way.


Small Pit or Hole in Tooth

If your cavity has progressed enough without getting it filled, it’s possible that you could see a small hole in the affected tooth. If you’re experiencing tooth pain, sensitivity, or any other symptom accompanied with a small visible dent, there’s a good chance you may have a cavity. A dentist will easily be able to tell you if it’s a cavity or not, and fill the hole if it is.


Persistent Bad Breath

Dealing with bad breath isn’t enjoyable for anyone, and it can be frustrating when it won’t go away. If you have bad breath that doesn’t get better with flossing, brushing your teeth, using mouthwash, or your other usual methods, this could be due to a cavity. Cavities are breeding grounds for bacteria, which can usually have a foul odor to them. You may also be experiencing a consistent bad taste in your mouth that you can’t get to go away.

Just like any dental issue, the sooner you get it checked out, the better. If you do have a cavity, catching it before it becomes deeper or more serious will require a less invasive and time-consuming filling. Dental decay can lead to much more serious problems, so if you think you may have a cavity, we encourage you to visit our family dentist in Evanston to get it examined. We’re just a call, click or drive away, so don’t delay your appointment!

Pregnancy is a time of excitement, anticipation, and transformation. As your body adapts to nurture new life, your needs evolve—including your dental care. At Stephens Dentistry, we’re passionate about supporting expectant mothers through every stage of this journey. Understanding the connection between oral health and pregnancy is not just important for your smile, but for the wellbeing of both you and your baby.  How Pregnancy Impacts Oral Health Pregnancy brings about a surge in hormones, especially estrogen and progesterone, which can have a profound effect on your gums and teeth. Many women notice changes in their oral health during pregnancy, including increased sensitivity, swelling, or bleeding gums. These shifts aren't just uncomfortable—they can also signal conditions that need attention to safeguard your overall health. Pregnancy Gingivitis: What You Need to Know One of the most common dental issues during pregnancy is pregnancy gingivitis. According to the Centers for Disease Control and Prevention , up to 60–75% of pregnant women develop gingivitis, which is characterized by red, swollen, and bleeding gums. This occurs because hormonal changes heighten the body’s response to the bacteria in dental plaque. If left untreated, gingivitis can progress to periodontitis—a more serious gum infection that can cause tooth loss and has been linked to health risks beyond the mouth. Oral Health and Birth Outcomes The importance of oral health during pregnancy goes beyond comfort and aesthetics. Research has shown a significant link between maternal gum disease and adverse pregnancy outcomes, such as preterm birth and low birth weight. A systematic review published in the Journal of Dental Research found that women with periodontal disease may be more likely to deliver prematurely or have babies with low birth weights. Although more research is ongoing, the potential connection means that taking care of your gums and teeth is an essential part of prenatal health. Why Dental Care Shouldn’t Wait Some expectant mothers worry about dental treatments during pregnancy. The good news is that routine dental care—including cleanings and necessary treatments—are not only safe but recommended during pregnancy. The American College of Obstetricians and Gynecologists confirms that preventive dental work is important and can be performed safely, especially in the second trimester. Delaying care can allow small problems to become bigger ones, and untreated infections can pose a risk to both you and your baby. If you are planning to become pregnant, scheduling a dental checkup beforehand is an excellent way to get ahead of any issues. Practical Tips for Expectant Mothers Maintaining oral health during pregnancy doesn’t have to be complicated. Here are some tips to keep your smile healthy throughout your pregnancy: Brush and Floss Regularly: Aim to brush twice a day with fluoride toothpaste and floss daily. This helps remove plaque and reduce your risk of gingivitis. Eat a Balanced Diet: Focus on nutritious foods rich in calcium, vitamin D, and protein, which support both your oral and overall health. Manage Morning Sickness: If you experience vomiting, rinse your mouth with water or a fluoride mouthwash rather than brushing immediately afterward, as stomach acid can soften tooth enamel. Stay Hydrated: Drinking plenty of water helps wash away food particles and bacteria, and can also help combat dry mouth, which is common in pregnancy. Schedule Regular Dental Visits: Let your dental team know you are pregnant so they can tailor your care. At Stephens Dentistry, we take extra precautions to ensure your comfort and safety during each visit. Learn more about our preventive dental services . Recognizing When to Call Your Dentist While mild gum sensitivity is common, it’s important to reach out to your dentist if you notice persistent bleeding, swelling, or pain. These symptoms could indicate an infection that needs prompt attention. If you develop a dental emergency during pregnancy, don’t hesitate to contact your dentist—timely care is always the best choice for both you and your baby.
