What Happens If You Ignore a Cavity?

It starts small—a dull ache, a little sensitivity to sweets, or perhaps no symptoms at all. But cavities (also called dental caries) don’t stay small for long. At Landman Dentistry By the Lake in Mahopac, NY, we often see patients who delay treatment, not realizing how quickly tooth decay can progress.

So what does happen if you ignore a cavity?

Let’s explore the stages of untreated tooth decay—and how early care can save your smile, your comfort, and your wallet.

Stage 1: Enamel Erosion

Cavities begin when plaque—a sticky film of bacteria—interacts with sugars in your diet, producing acid that wears away the enamel (the outer protective layer of the tooth). In this earliest stage:

● The damage may be microscopic

● You might not feel any pain

● White spots or chalky areas may appear

Good news: At this point, fluoride treatment and better hygiene might reverse or stop the decay.

Stage 2: Dentin Decay

If left untreated, the decay breaks through the enamel and reaches the dentin (the sensitive middle layer). Here’s what can happen:

● Increased tooth sensitivity

● Sharp pain with hot, cold, or sweet foods

● Discoloration or small holes

This is typically when a dental filling is needed. Fortunately, fillings are quick, cost-effective, and can restore the tooth’s integrity when caught early.

Stage 3: Pulp Infection

The pulp is the innermost part of your tooth, where nerves and blood vessels live. If decay reaches the pulp:

● You may experience constant, throbbing pain

● Swelling or tenderness in the gums may appear

● The tooth may become abscessed (infected)

At this point, a root canal is usually necessary to save the tooth—and ignoring it any longer could lead to a dental emergency.

Stage 4: Tooth Loss or Extraction

When infection spreads and damages the surrounding bone or gum tissue, your tooth may no longer be salvageable. The only option may be:

● Tooth extraction

● Dental implants, bridges, or dentures to replace the lost tooth

This is not only more costly and time-consuming, but it also puts neighboring teeth and your bite at risk.

The Bigger Picture: Oral Health and Your Whole Body

Untreated cavities don’t just stay in your mouth. The bacteria that cause decay can:

● Enter the bloodstream and affect the heart (endocarditis)

● Complicate diabetes control

● Trigger systemic inflammation

Chronic oral infections also weaken the immune system, especially in older adults, pregnant women, and children.

Prevention Is Always Easier (and Cheaper)

A small cavity caught early = one quick visit, minimal cost, and a restored smile.

A cavity ignored = multiple appointments, discomfort, and more invasive (and expensive) treatment.

The takeaway? Don’t wait for pain. Cavities are easiest to treat when they’re still small.
