Tooth Decay Treatment in Brampton | Cavity Treatment & Rotten Teeth | Polaris Dental
Are you looking for tooth decay treatment in Brampton? Do you have rotting teeth, cavity teeth, or think you may have cavities and tooth decay? At Polaris Dental, we provide comprehensive treatment for all stages of tooth decay, from small cavities to severely damaged teeth. Our goal is always to save your natural teeth whenever possible while relieving pain and restoring your oral health.
Tooth decay is one of the most common dental conditions affecting both children and adults. When treated early, most cavities can be repaired quickly with simple fillings. However, delaying treatment can allow the decay to spread deeper into the tooth, resulting in infection, severe pain, root canal treatment, or even tooth extraction.
If you have a toothache, visible holes in your teeth, sensitivity, or dark spots, don’t wait—early treatment is the best way to protect your smile.
What Is Tooth Decay?
Tooth decay, also called dental caries or cavities, occurs when bacteria in your mouth produce acids that gradually dissolve the protective enamel of your teeth.
Every time you eat sugary or starchy foods, bacteria feed on these particles and create acid. Over time, repeated acid attacks weaken the enamel, allowing cavities to develop.
Without treatment, tooth decay continues to spread through the deeper layers of the tooth, eventually reaching the nerve and causing infection.
What Causes Cavities and Tooth Decay?
Several factors increase the risk of developing cavities, including:
- Poor brushing and flossing
- Frequent consumption of sugary foods and drinks
- Dry mouth
- Plaque buildup
- Skipping regular dental cleanings
- Acidic beverages
- Smoking or tobacco use
- Deep grooves in teeth
- Worn or leaking dental fillings
Regular dental examinations allow dentists to detect decay before it becomes painful.
Signs You May Need Tooth Decay Treatment
Many cavities cause no symptoms in their early stages. As decay progresses, you may notice:
- Tooth sensitivity to hot, cold, or sweet foods
- Toothache
- Pain when biting
- Dark or brown spots on teeth
- Visible holes in the tooth
- Bad breath
- Food getting stuck in the tooth
- Swelling around the tooth
- Broken teeth caused by weakened enamel
If you experience any of these symptoms, schedule a dental examination as soon as possible.
What Are Rotting Teeth?
The term rotting teeth refers to teeth that have been severely damaged by untreated tooth decay. As cavities become larger, the tooth structure weakens and may begin to crumble or break apart.
Rotting teeth may cause:
- Severe tooth pain
- Bad breath
- Infection
- Gum swelling
- Facial swelling
- Difficulty chewing
- Broken teeth
- Tooth abscesses
Although the term sounds alarming, many severely decayed teeth can still be saved if treated early enough.
Can a Rotten Tooth Be Saved?
It depends on how much healthy tooth structure remains.
At Polaris Dental, we always try to preserve your natural tooth whenever possible.
Treatment options may include:
Tooth-Coloured Fillings
Small cavities can often be repaired using natural-looking composite fillings that blend seamlessly with your teeth.
Dental Crowns
If a large portion of the tooth has been damaged, a custom dental crown may restore its strength and appearance.
At Polaris Dental, we use the advanced iTero® digital scanner to capture highly accurate 3D images of your teeth. This technology allows us to create precise, comfortable, and natural-looking crowns without messy traditional impressions.
Root Canal Treatment
If tooth decay reaches the dental pulp (nerve), root canal treatment may eliminate the infection while preserving the tooth.
After root canal treatment, a dental crown is often recommended to strengthen the tooth and reduce the risk of fracture.
Tooth Extraction
If the tooth is too severely damaged to be restored predictably, extraction may be the safest option.
If extraction is necessary, we will discuss tooth replacement options such as:
- Dental bridges
- Partial dentures
- Complete dentures
Our goal is to restore both your oral health and your smile.
What Happens If Tooth Decay Is Left Untreated?
Ignoring cavities can lead to serious complications, including:
- Larger cavities
- Severe toothaches
- Dental abscesses
- Gum infections
- Tooth fractures
- Root canal treatment
- Tooth loss
- Difficulty eating
- Spread of infection into surrounding tissues
Treating decay early is usually simpler, less invasive, and more affordable.
How We Diagnose Tooth Decay
At Polaris Dental, we use modern diagnostic technology to detect cavities accurately.
Your examination may include:
- Comprehensive oral examination
- Digital dental X-rays
- Clinical evaluation
- Bite assessment
- Existing filling evaluation
- Gum examination
Early diagnosis allows us to treat cavities before they become painful or require more extensive procedures.
How Is Tooth Decay Treated?
The appropriate treatment depends on how advanced the decay has become.
Early Decay
Very early decay may sometimes be managed with fluoride treatment, improved oral hygiene, and dietary changes before a cavity forms.
Small Cavities
Small cavities are repaired with tooth-coloured composite fillings.
Moderate Decay
Larger cavities may require an inlay, onlay, or dental crown.
Deep Decay
When decay reaches the nerve, root canal treatment followed by a dental crown is often recommended.
Severe Tooth Decay
When the tooth cannot be restored, extraction may be necessary to eliminate infection and relieve pain.
Preventing Cavities and Tooth Decay
Good oral hygiene and preventive dental care are the best defenses against tooth decay.
We recommend:
- Brushing twice daily with fluoride toothpaste
- Flossing every day
- Limiting sugary snacks and beverages
- Drinking plenty of water
- Scheduling regular dental cleanings
- Visiting your dentist every six months
- Using fluoride products when recommended
Preventive care helps reduce the need for more complex dental treatment in the future.

Frequently Asked Questions
Can tooth decay be reversed?
Very early enamel damage may sometimes be reversed with fluoride and improved oral hygiene. Once a cavity forms, professional dental treatment is necessary.
Is tooth decay contagious?
The bacteria that contribute to tooth decay can be transferred between people, but cavities themselves are not contagious.
Are fillings painful?
Modern fillings are typically comfortable. Local anesthesia is used whenever necessary to ensure a painless experience.
How do I know if I need a root canal?
If decay has reached the nerve, you may experience severe pain, prolonged sensitivity, swelling, or infection. Your dentist will determine whether root canal treatment is needed after an examination.
