A dental filling is commonly used when tooth decay or minor tooth damage needs to be repaired. Many patients do not realise they may need a filling until a cavity becomes larger, painful or sensitive.
Seeing a dentist early can help identify decay before it becomes more serious and may reduce the chance of needing more complex treatment later.
What is a dental filling?
A dental filling repairs a tooth after decay or damaged tooth structure has been removed. The filling material restores the tooth’s shape and helps protect the area from further breakdown.
Fillings are often used for small to moderate cavities, chipped areas or worn parts of teeth, depending on the condition of the tooth.
Common signs you may need a filling
You may need a dental assessment for a possible filling if you notice:
- Tooth sensitivity to cold, sweet or hot foods and drinks
- Pain when biting or chewing
- A visible dark spot, hole or pit in a tooth
- Food getting stuck in the same area repeatedly
- A rough or sharp edge on a tooth
- A chipped or cracked area
- Bad taste or smell from one tooth area
- Floss shredding or catching between teeth
Can tooth decay happen without pain?
Yes. Early tooth decay may not cause pain. A cavity can slowly grow without obvious symptoms, especially if it starts between teeth or under an old filling.
This is one reason regular dental check-ups are useful. Your dentist can look for early decay and may recommend X-rays where needed.
What happens if tooth decay is left untreated?
If decay is not treated, it can spread deeper into the tooth. A small cavity may become a larger cavity, and the tooth may eventually become painful, infected or weakened.
In some cases, untreated decay may lead to the need for root canal treatment, a crown or extraction.
How does the dentist check for decay?
Your dentist will examine the teeth, check around fillings, assess symptoms and may recommend dental X-rays to check between teeth or under existing restorations.
The dentist can then explain whether monitoring, prevention, a filling or another treatment may be suitable.
Is every dark spot a cavity?
No. Dark spots can be caused by staining, old fillings, enamel changes or other factors. However, it is difficult to know without a dental assessment.
If you see a new dark spot, hole or rough area, it is best to have it checked.
Can a filling fix every cavity?
Not always. A filling may be suitable for many small to moderate cavities. If the tooth is badly broken, cracked, heavily decayed or weakened, a crown, root canal treatment or other option may be needed.
Your dentist will explain the options after assessing the tooth.
How can you reduce the risk of needing fillings?
Brush twice daily with fluoride toothpaste, clean between your teeth, limit frequent sugary snacks and drinks, drink water, and attend regular dental check-ups.
Children and adults with higher decay risk may need personalised preventive advice.
