What happens if you leave a cavity untreated? From fillings to root canal
Tooth decay is one of the most common oral health issues experienced by both children and adults. Left unchecked, a simple cavity can evolve into a much more serious dental concern. But what actually happens if a cavity is left untreated? This article explores how decay progresses, the signs to watch for, and the treatment pathways that may be recommended by your dentist in Dubbo, from fillings to root canal therapy.
What is a cavity and how does it start?
A cavity is essentially a small hole in the tooth caused by the breakdown of enamel due to bacterial activity. Oral bacteria feed on sugars and starches, producing acids that erode the tooth's outer layer. Over time, this can lead to enamel erosion and deeper penetration into the softer dentine beneath.
Early-stage tooth decay may not cause discomfort, which is why regular check-ups in Dubbo are essential. When left untreated, cavities can silently grow larger, potentially compromising the entire tooth structure. To understand more about how cavities develop, read our detailed guide on what is a cavity.
How does decay progress if left untreated?
If a cavity isn't addressed early, the damage can move through the following stages:
Enamel erosion: The outer protective layer of the tooth begins to weaken.
Dentine exposure: As decay reaches the dentine, it can cause increased tooth sensitivity.
Pulp inflammation: Once bacteria reach the dental pulp (which contains nerves and blood vessels), severe pain and inflammation can occur.
Infection or abscess: The tooth may develop an infection, leading to swelling, pus formation, or even systemic health issues.
In some cases, untreated dental caries can result in the need for urgent intervention, including root canal therapy or tooth extraction.
What symptoms might indicate a worsening cavity?
Recognising early signs of a worsening cavity can help avoid more invasive procedures. Common symptoms include:
- Sensitivity to hot, cold, or sweet foods and drinks
- Pain when biting or chewing
- Visible holes or pits in the tooth
- Persistent toothache
- Swelling around the gums or jaw
If any of these symptoms are present, it is important to seek dental advice promptly. Learn more about different types of dental pain and what they might indicate.
What are the treatment options based on decay severity?
Cavity treatment depends on the stage of progression. Here are common interventions:
| Stage of Decay | Symptoms | Possible Treatment |
|---|---|---|
| Early enamel decay | Mild sensitivity | Fluoride treatment / filling |
| Dentine involvement | Moderate pain, visible damage | Filling or inlay/onlay |
| Pulp exposure | Severe pain, swelling | Root canal therapy |
| Abscess formation | Throbbing pain, fever, bad taste | Root canal or extraction + antibiotics |
Each treatment is aimed at preserving as much of the natural tooth as possible while preventing further infection or damage. For early-stage decay, fillings in Dubbo can effectively restore tooth structure and function.
What are the risks of ignoring a cavity?
Neglecting a cavity can lead to significant oral and overall health issues, including:
- Irreversible nerve damage requiring complex procedures
- Spread of bacteria to adjacent teeth
- Development of an abscess, which can cause fever and discomfort
- Tooth loss due to structural collapse
- Risk of bacteria entering the bloodstream, potentially affecting other organs
These complications highlight the importance of early dental intervention. Understanding the effects of poor oral health can motivate better preventative care habits.
What can you do to prevent cavities from forming or worsening?
Preventative dentistry plays a vital role in managing oral health. To reduce your risk of developing cavities:
- Brush teeth twice daily using fluoride toothpaste
- Floss daily to remove debris between teeth
- Limit sugary and acidic foods and drinks
- Attend routine dental check-ups and hygiene visits
- Ask your dentist about fissure sealants and fluoride treatments
Maintaining strong oral hygiene habits is one of the best defences against dental caries. Our article on how to choose the right mouthwash for your needs can further support your preventative routine.
How can untreated decay affect neighbouring teeth and gums?
Once a tooth becomes severely decayed, nearby teeth and gum tissues may be at risk. Bacteria can migrate, leading to:
- Spread of infection to adjacent teeth
- Gum inflammation and bleeding
- Bone loss around affected areas
- Widening of decay zones due to compromised enamel in surrounding teeth
Addressing cavities early can help protect your entire mouth. Gum health is particularly important, as discussed in our blog about how gum health is linked to heart disease.
When might a root canal be needed?
Root canal therapy is typically recommended when decay reaches the pulp, causing inflammation or infection. Signs that may indicate the need for this treatment include:
- Persistent or throbbing pain
- Lingering sensitivity to hot or cold
- Discolouration of the tooth
- Tenderness or swelling near the gums
The procedure involves removing the infected tissue, disinfecting the area, and sealing the tooth to preserve its function. For comprehensive information, explore our guide on what is a root canal and its benefits, or if you're concerned about discomfort, read about whether root canals are painful.

Frequently Asked Questions (FAQs)
1. Can a cavity heal on its own without treatment?
No. Once a cavity has formed, it cannot regenerate or heal naturally. Treatment is necessary to prevent further decay. Learn more about what causes teeth cavities.
2. How long can a cavity go untreated before it becomes serious?
This varies, but untreated cavities can progress rapidly, especially if oral hygiene is poor. Damage may occur within months.
3. What happens during a root canal procedure?
A root canal involves removing infected pulp tissue, cleaning the tooth's internal canals, and sealing it to restore structure and prevent reinfection. For a visual understanding, check out what does a root canal look like.
4. Can an untreated cavity lead to tooth extraction?
Yes. If decay is extensive and the tooth is too damaged to restore, extraction may be the only option. Our article on when tooth extraction is necessary provides more details.
5. Does every cavity eventually require a root canal?
No. Many cavities can be treated early with simple fillings. Root canals are only needed when decay reaches the pulp. Read about whether cavities are always painful.
6. Is tooth pain always a sign of a cavity?
Not necessarily, but persistent or worsening pain should always be assessed by a dental professional to rule out decay or other issues.
