No one likes the idea of getting a cavity — but the truth is, cavities are one of the most common dental problems. In fact, according to the CDC, over 90% of adults have had at least one cavity in their lifetime. The good news? Cavities are treatable — especially when caught early.

At Mountain Aire Dentistry in Broomfield, CO, we believe that staying informed is the first step to protecting your smile. If you’ve been wondering whether that toothache or sensitivity means something more, this blog is for you.

Here are 5 common signs you may have a cavity — and how our dental team can help restore your smile quickly and comfortably.

1. Tooth Sensitivity

Do you feel a sharp twinge when you eat or drink something hot, cold, or sweet? That could be a sign of a cavity forming.

What it means:

When tooth enamel starts to break down, the sensitive layer underneath (called dentin) becomes exposed. This makes the tooth more reactive to temperature changes or certain foods.

How we can help:

We’ll examine the area, take digital X-rays if needed, and determine whether a filling is required. Catching it early means we can treat the cavity before it gets worse — often with a quick, pain-free filling.

2. Toothache or Ongoing Pain

A sudden toothache or throbbing pain that doesn’t go away could be a sign of decay reaching deeper into the tooth.

What it means:

If a cavity isn’t treated early, it can reach the inner pulp of the tooth — where the nerves and blood vessels live. This can cause ongoing discomfort or even infection.

How we can help:

Don’t try to “tough it out.” A thorough exam will help us find the root of the pain. In more advanced cases, we may recommend a root canal to clean out the infection and save the tooth. Our goal is to stop the pain and keep your smile healthy.

3. Visible Holes or Dark Spots on Your Teeth

Sometimes, cavities show up as visible changes to the surface of your tooth — such as small pits, holes, or brown/black spots.

What it means:

This is often a sign of enamel erosion caused by plaque and acid attacking the tooth over time.

How we can help:

We’ll gently clean out the decay and fill the tooth with a tooth-colored filling that blends in perfectly with your natural smile. You’ll leave with your tooth restored and protected from further damage.

4. Bad Breath or a Bad Taste That Won’t Go Away

Persistent bad breath (halitosis) or a foul taste in your mouth may signal a cavity — especially if it’s accompanied by other symptoms like pain or sensitivity.

What it means:

Bacteria trapped in decayed areas of a tooth can create unpleasant odors and tastes, even if you’re brushing regularly.

How we can help:

We’ll check for cavities and clean out any areas of decay or buildup. Along with treating the cavity, we’ll guide you on better oral hygiene habits to keep your mouth fresh and healthy.

5. Pain When You Bite Down

If you feel pain or pressure when chewing or biting, it could mean that decay has weakened your tooth or affected the nerve inside.

What it means:

This is often a sign of more advanced decay. Biting pressure can aggravate the sensitive inner parts of the tooth or signal a crack caused by a cavity.

How we can help:

Depending on the severity, we may recommend a filling, crown, or root canal. Our priority is to relieve your pain and restore your ability to chew comfortably.

What Causes Cavities?

Cavities develop when plaque — a sticky film of bacteria — builds up on your teeth and produces acid. This acid slowly breaks down tooth enamel, eventually creating holes or “caries” (another word for cavities).

Factors that increase your risk include:

• Poor brushing or flossing habits

• High-sugar diet or frequent snacking

• Dry mouth (reduced saliva makes it easier for bacteria to grow)

• Lack of regular dental cleanings

• Deep grooves in teeth that are hard to clean
