Most people don’t know they have a cavity until it starts hurting—or until their dentist spots it during a checkup. Cavities start small and grow silently, and by the time you feel pain, the decay has already reached deeper layers of your tooth.
So how do you really know if you need a dental filling?
At Smile Dental in Stafford, TX, we help patients detect cavities early so treatment stays simple and affordable. In this guide, you’ll learn the signs you need a filling, what happens if you delay treatment, and how we make fillings quick and comfortable.
What Is a Dental Filling?
A dental filling is a treatment used to repair a tooth damaged by decay, fractures, or wear. During the procedure, the dentist removes the decayed area and fills it with a strong material such as composite resin, ensuring your tooth stays functional and protected.
Fillings stop the spread of decay and prevent future complications.
1. Tooth Sensitivity, Especially to Hot, Cold, or Sweets
Sensitivity is one of the earliest signs of a cavity.
You may feel:
- A sharp “zing” when drinking cold water
- Sensitivity when eating sweets
- Mild pain when consuming hot foods
This happens because the enamel has weakened, exposing the inner layer of the tooth (dentin).

2. Sudden Toothache or Throbbing Pain
If you feel a dull ache, sharp pain, or pressure in a tooth, it may indicate that decay has reached deeper layers.
Typical signs:
- Pain when chewing
- Random throbbing
- Pain that gets worse at night
- Pain during meals
Toothaches usually mean the cavity has advanced and needs immediate attention.
3. Visible Dark Spots or Holes in Your Tooth
You might notice:
- Brown, black, or dark white discoloration
- Tiny pits or holes
- Rough areas on the tooth surface
These visible changes are signs of decay. The earlier a dentist evaluates these spots, the less invasive treatment will be.
4. Food Getting Stuck in One Spot
If food keeps getting stuck in the same area, it may indicate a cavity or a gap caused by decay.
Symptoms include:
- Needing to floss repeatedly
- Food packing between teeth
- Localized soreness
This can lead to gum irritation and worsen the cavity if not treated.
5. Chipped or Cracked Tooth
A small crack or chip can expose the sensitive inner layers of your tooth, increasing the risk of decay.
You may notice:
- Sensitivity when biting
- Sharp edges
- Pain when chewing
A filling can restore strength and prevent further damage.

6. Rough or Sharp Tooth Surface
If you feel a rough edge with your tongue, it may indicate enamel erosion or the start of a cavity.
This usually appears on:
- Molars
- Between teeth
- Old fillings that have worn down
A new filling can restore smoothness and protect the tooth.
7. Bad Breath or Persistent Bad Taste
Cavities trap bacteria and food particles, which cause:
- Halitosis
- Metallic taste
- Bad taste even after brushing
If bad breath stays even after cleaning your mouth, it may be due to decay.
8. Existing Fillings Are Cracked or Loose
Old fillings can wear down over time. If you notice:
- Tooth sensitivity
- Pain around old fillings
- Food getting stuck
- Visible lines or cracks
…it’s time to replace the filling before decay forms underneath.

What Happens If You Ignore a Cavity?
Delaying a filling can lead to serious dental problems, including:
1. Larger cavities
Decay spreads quickly.
2. Pain & sensitivity
Once decay reaches the dentin or nerve, pain increases.
3. Infections or abscess
This may require antibiotics and emergency treatment.
4. Root canal treatment
Untreated cavities eventually reach the nerve.
5. Tooth loss
Severe decay can make saving the tooth impossible.
A simple filling is faster, cheaper, and less painful than advanced treatments.
