Have you ever felt a sudden toothache or noticed a tiny black spot on your tooth and wondered, “What does a cavity look like?” You’re not alone! Cavities, also called dental caries, are one of the most common dental problems worldwide.
They can start small and barely noticeable, but if left untreated, they can grow, causing pain and even infection.
Quick Answer:
A cavity is a hole or damage in your tooth caused by decay. It usually looks like a dark spot, pit, or hole on the tooth surface. Cavities are common, preventable, and treatable with the right dental care.
🧠 What Does a Cavity Look Like?
A cavity begins when plaque — a sticky film of bacteria — produces acids that erode your tooth enamel. This damage can appear in several ways:
- White spots: Early stage, decalcification of enamel.
- Brown or black spots: More advanced decay.
- Holes or pits: Obvious cavities where enamel and dentin have broken down.
- Rough or jagged edges: A sign you might feel with your tongue.
Example:
You might notice a tiny black dot on your molar that wasn’t there before — that could be an early cavity forming.
In short:
Cavity = Tooth Decay = Dark Spot, Hole, or Damage on Tooth Surface
📱 Where Are Cavities Most Commonly Found?
Cavities can appear on any tooth surface, but some areas are more prone:
- Molars and premolars:
- Grooves and pits trap food easily 🍬
- Between teeth:
- Hard to clean, plaque builds up
- Near the gum line:
- Acid damage weakens enamel
Casual dental tip:
Cavities aren’t “contagious,” but sugar + poor brushing makes them likely. 🪥
Formality:
Cavities are discussed in healthcare and dental settings, casual conversation among friends, or parenting advice.
💬 Examples of What Cavities Look Like in Real Life

Comparison Table:
| Context | Example Observation | Why It Matters |
|---|---|---|
| Early Spot | White or brown dot on tooth | Can be reversed with fluoride |
| Small Hole | Tiny pit on molar | Needs filling to prevent worsening |
| Painful Cavity | Sharp pain when biting sweets | Requires dentist intervention |
| Advanced Decay | Large dark hole with sensitivity | Possible root canal needed |

| Cracked Tooth | Visible line or piece chipped | Dentist ASAP to prevent decay |
❓ FAQs About Cavities
Q1: Can you see a cavity without a dentist?
Yes, early cavities might be hard to see, but larger ones appear as black/brown spots, pits, or holes. Your dentist can confirm with an exam or X-ray.
Q2: Do cavities hurt immediately?
Not always. Small cavities may cause no pain at first, but sensitivity develops as decay reaches deeper layers of the tooth.
Q3: Can cavities heal on their own?
Early-stage enamel demineralization can sometimes be reversed with fluoride toothpaste and proper oral hygiene. Holes or deep decay cannot heal without treatment.
Q4: What foods cause cavities?
Sugary and sticky foods, sodas, and frequent snacking increase plaque and acid, leading to cavities.
Q5: How are cavities treated?
Treatment includes fillings, crowns, or root canals depending on severity. Regular dental visits prevent progression.
📝 Conclusion
Recognizing cavities early is key to preventing pain, infection, and costly dental work. They can appear as white spots, dark brown or black areas, holes, or rough edges on your teeth.
Most cavities form in grooves, between teeth, or near the gum line — areas prone to food and plaque buildup. Early action, proper brushing and flossing, reducing sugary snacks, and regular dental visits can reverse minor decay or stop it from worsening.
If you notice any signs like sensitivity, discoloration, or pain, see your dentist promptly. Remember: catching a cavity early makes treatment simple and painless. 🦷
