Tooth decay is one of the most common dental issues, affecting people of all ages. Often starting as a minor problem, it can progress into a serious condition if left untreated. Decay occurs when plaque, a sticky film of bacteria, accumulates on teeth and produces acids that erode the enamel.
Recognising the early signs of tooth decay is key to preventing further damage and maintaining a healthy smile. Whether it’s a subtle change in tooth colour or noticeable discomfort, being aware of these signs can make all the difference.
What Does a Decaying Tooth Look Like?
Tooth decay often starts subtly, but as it progresses, the signs become more noticeable. Here are some key visual indicators that may suggest a tooth is decaying:
Discoloration
- One of the earliest signs of decay is a change in the colour of your tooth.
- This may appear as white spots caused by demineralisation or progress to yellow, brown, or black patches as the enamel breaks down.
Visible Cavities or Pits
- As the decay worsens, small holes or pits may form in the tooth.
- These cavities can range from tiny, hard-to-detect spots to larger visible gaps, especially on the chewing surfaces or between teeth.
Rough or Uneven Surfaces
- A healthy tooth has a smooth, even surface.
- Decay can cause the enamel to erode, leaving the tooth feeling rough, jagged, or chipped.
Accumulation of Plaque and Tartar
- A decaying tooth may have a buildup of plaque or hardened tartar around the affected area.
- This is often a sign that decay has been progressing for some time.
Swelling or Redness in Surrounding Gums
- Although not part of the tooth itself, gum inflammation around a decaying tooth is a common sign. This can occur due to irritation or infection caused by the decay.
The Stages of Tooth Decay
Tooth decay progresses through distinct stages, each with its own set of signs and symptoms. Understanding these stages can help you recognise decay early and seek timely treatment.
Initial Demineralisation
- What Happens: The first stage of tooth decay occurs when acids from plaque begin to strip minerals from the enamel. This weakens the tooth’s protective layer.
- Signs: You may notice white spots on the surface of the tooth, particularly near the gum line.
- Action: At this stage, decay can often be reversed with fluoride treatments and better oral hygiene.
Enamel Decay
- What Happens: As demineralisation progresses, the enamel starts to break down, forming small cavities.
- Signs: Discoloration such as yellow or brown stains and sensitivity to hot, cold, or sweet foods.
- Action: A filling is usually required to repair the damage and prevent further decay.
Dentin Decay
- What Happens: Once the enamel is compromised, decay reaches the dentin, the softer layer beneath the enamel. This allows bacteria to spread more quickly.
- Signs: Increased sensitivity, visible holes or pits, and pain when biting or chewing.
- Action: Immediate dental intervention is necessary to prevent the decay from spreading deeper.
Pulp Damage
- What Happens: If left untreated, decay can penetrate the pulp, the innermost part of the tooth that contains nerves and blood vessels. This often leads to infection.
- Signs: Persistent and severe tooth pain, swelling, and sometimes the formation of an abscess.
- Action: A root canal or tooth extraction may be required at this stage.
Abscess Formation
- What Happens: The infection can spread beyond the tooth, forming a pus-filled abscess that affects surrounding tissues.
- Signs: Severe pain, swelling in the gums or face, fever, and a foul taste in the mouth.
- Action: Immediate treatment is critical to prevent complications. Antibiotics and surgical drainage may be required, along with a root canal or extraction.
Symptoms That Accompany Tooth Decay
Tooth decay is not always immediately visible, but it often comes with symptoms that can alert you to a problem. Recognising these signs early can prevent more serious dental issues.
Tooth Sensitivity
- A decaying tooth often becomes sensitive to hot, cold, or sweet foods and drinks.
- This sensitivity may start as a mild discomfort but can worsen over time.
Persistent Toothache
- A continuous or recurring toothache is a common symptom of advanced decay.
- The pain may range from dull and throbbing to sharp and severe, especially when eating or biting down.
Discomfort When Chewing
- Pain or discomfort when chewing or applying pressure to a specific tooth could be a sign of a cavity or deeper decay.
Bad Breath or Unpleasant Taste
- Bacteria from decay can produce an unpleasant odour or taste in the mouth that doesn’t go away with brushing.
Visible Changes in the Tooth or Gums
- In addition to discoloration or holes in the tooth, you might notice swelling, redness, or bleeding in the gums near the affected area.
General Discomfort in the Mouth
- A feeling of pressure or discomfort in the area of the decaying tooth may signal a deeper issue.
How to Prevent Tooth Decay
Preventing tooth decay is easier than treating it, and with a few simple habits, you can maintain strong, healthy teeth for life. Here are some effective ways to keep decay at bay:
Brush and Floss Daily
- Brush your teeth twice a day using fluoride toothpaste. Fluoride helps strengthen enamel and prevent demineralisation.
- Floss daily to remove food particles and plaque from between teeth where your toothbrush can’t reach.
Maintain a Healthy Diet
- Limit sugary and acidic foods and drinks, as they contribute to the formation of harmful plaque acids.
- Incorporate tooth-friendly foods like dairy products, leafy greens, and crunchy fruits and vegetables that promote saliva production and help clean teeth naturally.
Use Fluoride Treatments
- Fluoride is a powerful tool for preventing tooth decay. Use a fluoride mouthwash or ask your dentist about professional fluoride treatments for added protection.
Stay Hydrated
- Drinking water, especially fluoridated water, helps rinse away food particles and neutralise acids in your mouth.
Regular Dental Check-Ups
- Schedule routine check-ups and cleanings with Dentistry on Coolum to catch early signs of decay and prevent more serious dental issues.
- Your dentist can also apply sealants to protect vulnerable areas of your teeth from decay.
Avoid Smoking and Alcohol
- Smoking and excessive alcohol consumption can weaken your teeth and gums, making them more susceptible to decay.
Protect Your Teeth During Sports
- Wear a mouthguard during contact sports to prevent damage that could lead to decay.
