What Happens During a Dental Filling Procedure?
- March 19, 2026
Hearing that you need a dental filling can make some people feel nervous, especially if they are unsure about what the procedure involves.
The good news is that dental fillings are one of the most common and straightforward treatments in modern dentistry.
A dental filling is used to repair a tooth that has been damaged by decay or minor cracks. The dental filling procedure removes the unhealthy portion of the tooth and restores its structure with a strong filling material.
At a professional Subiaco dental clinic, dental fillings are designed to be quick, comfortable, and effective.
Why You Might Need a Dental Filling?
Dental fillings are usually recommended when a cavity forms due to tooth decay. Bacteria in plaque produce acids that slowly wear away the enamel, creating small holes in the tooth.
If untreated, these cavities can grow larger and eventually cause pain or infection.
Signs you may need a filling include:
- Tooth sensitivity to hot, cold, or sweet foods
- A visible hole or dark spot on the tooth
- Sharp pain when biting or chewing
- Food frequently gets stuck in the same area
A dental examination at a Subiaco dental clinic can confirm whether a filling is needed.
Step-by-Step: What Happens During a Dental Filling Procedure
1. Dental Examination and Diagnosis
The process begins with a thorough dental examination. The dentist checks the affected tooth and may take X-rays to determine how deep the decay extends.
Once the cavity is confirmed, the dentist will explain the procedure and discuss the best filling material for your tooth.
2. Numbing the Area
Before starting the treatment, the dentist applies a local anaesthetic to numb the area around the tooth.
This ensures the procedure is comfortable and pain-free. Most patients only feel slight pressure during the treatment rather than pain.
A skilled Subiaco dentist carefully administers the anaesthetic to keep you relaxed throughout the procedure.
3. Removing the Tooth Decay
After the area is numb, the dentist removes the decayed portion of the tooth using specialised dental instruments.
This step is essential because it eliminates bacteria and prevents the decay from spreading further.
Once the damaged material is removed, the tooth is thoroughly cleaned to prepare it for the filling.
4. Placing the Filling Material
The dentist then fills the cleaned cavity with a suitable material. Common filling materials include:
- Composite resin (tooth-coloured)
- Ceramic
- Glass ionomer
- Amalgam (metal filling)
Tooth-coloured composite fillings are widely used because they blend naturally with the surrounding teeth.
At a reputable Subiaco dental clinic, dentists often recommend materials that provide both durability and aesthetics.
5. Shaping and Polishing the Tooth
After the filling material is placed, the dentist shapes it carefully so that it matches the natural contours of your tooth.
The filling is then hardened using a special curing light (for composite fillings).
Finally, the dentist polishes the tooth to ensure a smooth finish and a comfortable bite.
How Long Does a Dental Filling Take?
Most dental filling procedures take 30 to 60 minutes, depending on the size and location of the cavity.
Smaller cavities may be completed more quickly, while larger fillings may require a little more time.
Your Subiaco dentist will ensure the procedure is completed carefully to protect the strength and structure of your tooth.
What to Expect After the Procedure
After the filling is complete, it is normal to experience mild sensitivity for a short period.
You may notice:
- Slight sensitivity to temperature
- Minor numbness until the anaesthetic wears off
- A different feeling when biting initially
These sensations typically disappear within a few days.
If discomfort continues, visiting your Subiaco dental clinic for an adjustment can ensure the filling sits correctly.
Tips for Taking Care of Your Dental Filling
Proper oral care helps fillings last for many years.
Helpful habits include:
- Brushing twice daily with fluoride toothpaste
- Flossing every day
- Limiting sugary snacks and drinks
- Attending regular dental checkups and cleanings
Routine visits allow a Subiaco dentist to monitor the filling and detect any issues early.
Frequently Asked Questions
- Are dental fillings painful?
No. Local anaesthesia numbs the area, so patients typically feel little to no pain during the procedure.
- How long do dental fillings last?
Depending on the material and oral care habits, fillings can last 5 to 15 years or longer.
- Can I eat after getting a filling?
You can usually eat once the numbness wears off. However, it is best to avoid very hard or sticky foods for the first few hours.
- What happens if a cavity is not treated?
Untreated cavities can grow larger and eventually lead to severe decay, infection, or the need for more complex treatments like root canals.
- Are tooth-coloured fillings better?
Tooth-coloured fillings are popular because they blend naturally with teeth and provide a strong, durable restoration.
