How to know when you need a tooth filling | 3 min read

Familiarise yourself with the key signs that indicate you may need a tooth filling, learn about the procedure, and explore preventative measures for maintaining optimal oral health.

Introduction

A toothache can be more than just a temporary discomfort—it might be your body’s way of telling you that you need a filling. Cavities and tooth decay are common dental issues, but many people ignore the early warning signs, leading to more severe problems down the line. By recognising the symptoms early, you can prevent further damage and avoid costly dental treatments. This guide will help you understand when a filling is necessary and what steps you can take to maintain a healthy smile.

What Is a tooth filling?

A dental filling is a common procedure used to restore a damaged or decayed tooth. When bacteria erode the enamel and create cavities, a filling helps to repair the affected area, preventing further deterioration. Fillings come in various materials, including composite resin, amalgam, gold, and ceramic, each with its own benefits and durability.

Signs you may need a tooth filling:

Tooth sensitivity

If you experience discomfort or sharp pain when consuming hot, cold, or sugary foods and drinks, this could be an indication of enamel erosion. As the enamel wears down, the underlying dentin becomes exposed, leading to increased sensitivity.

Persistent toothache

A lingering or spontaneous toothache is often a sign of decay reaching the inner layers of the tooth. Pain that occurs without an apparent cause should not be ignored, as it may indicate the need for a filling.

Visible holes or dark spots

If you notice small holes, pits, or discoloration on your teeth, it could be a sign of cavities. These visual changes often mean the enamel has been compromised, and a filling may be necessary to prevent further decay.

Pain when biting or chewing

Discomfort when applying pressure to a tooth, such as when eating, can signal damage or decay. If left untreated, this could lead to a cracked tooth or the need for more extensive dental work.

Food getting stuck between teeth

If food frequently gets lodged in a particular area, it could indicate a cavity or a damaged filling. This can lead to further decay and an increased risk of gum disease if not addressed promptly.

Flossing string tearing

If your dental floss consistently frays or tears when used between specific teeth, it could be due to a rough edge caused by decay or a fractured filling. This is another sign that a visit to the dentist is warranted.

What happens during a tooth-filling procedure?

The process of getting a filling is simple and typically involves the following steps:

Examination & diagnosis – Your dentist will examine the affected tooth, possibly using X-rays to determine the extent of the decay.
Removing decay – The decayed portion of the tooth is carefully removed, ensuring that only the damaged area is affected.
Cleaning & preparing the tooth – The cavity is thoroughly cleaned to prevent bacterial infection before the filling material is applied.
Placing the filling – The selected filling material is placed and shaped to match your natural tooth structure.
Polishing & finishing – The filling is polished to ensure a smooth and comfortable bite.

Preventing the need for fillings.

While fillings are effective at treating cavities, prevention is always better than cure. Here are some key steps to reduce the risk of tooth decay:

Maintain good oral hygiene – Brush at least twice daily with fluoride toothpaste and floss regularly.
Visit your dentist regularly – Routine check-ups help catch potential problems before they worsen.
Limit sugary foods and beverages – Excess sugar contributes to plaque buildup and cavities.
Use dental sealants – These protective coatings on molars can help prevent cavities in hard-to-reach areas.

Conclusion

Recognising the early warning signs of tooth decay can save you from more extensive and costly dental procedures. If you experience sensitivity, pain, or visible changes in your teeth, it’s important to schedule a dental check-up as soon as possible. With the right care and preventive measures, you can keep your teeth strong and healthy for years to come.
