A healthy smile is more than just a confidence booster, it plays a key role in overall oral health and well-being. But even with diligent brushing and flossing, cavities can still occur. Fortunately, dental advancements make it easy to restore a decayed tooth through a common and highly effective treatment: a tooth filling. This blog explores what a tooth filling is, the signs that indicate you might need one, the procedure involved, and what to expect afterward.
A tooth filling is a restorative dental treatment used to repair minor tooth damage, typically caused by decay (cavities) or trauma. The filling material is placed in the cleaned-out cavity of the affected tooth to restore its shape, function, and strength while preventing further decay or infection.
Common Types of Tooth Filling Materials
Your dentist will recommend the best material based on the location of the cavity, the extent of the decay, and your personal preferences.
Tooth fillings are not limited to fixing cavities, they also help repair worn, chipped, or cracked teeth. Here are some clear signs you may need a filling:
A persistent or sharp pain when eating or drinking, especially sweet, hot, or cold foods, can be a sign of decay reaching the inner layers of the tooth.
If you notice visible holes or discolouration on your teeth, it could be an early indication of decay.
If your tooth feels sensitive to temperature changes or pressure, decay may have compromised your enamel.
Accidents, grinding, or biting into hard foods can lead to chipped or cracked teeth. Fillings can help restore these teeth before further damage occurs.
If an existing filling becomes loose, worn out, or falls out, it must be replaced promptly to prevent infection or further decay.
Your dentist will first examine the tooth and may take X-rays to assess the extent of decay.
To ensure comfort, a local anaesthetic is administered to numb the affected area.
The decayed or damaged portion of the tooth is removed using a dental drill or laser, creating a clean area for the filling.
Once the decay is removed, the cavity is cleaned and shaped to hold the filling securely.
The selected material is inserted into the cavity. If a composite resin is used, it is applied in layers and hardened with a special curing light.
After the filling sets, the dentist will polish the tooth and make necessary adjustments to ensure your bite feels natural.
Most people resume their normal activities shortly after getting a filling. However, some mild sensitivity or discomfort is normal and should subside in a few days.
In general, tooth fillings can last 5–15 years or longer, depending on the material used and your oral hygiene habits.
Proper oral care can extend the life of your filling and prevent further decay. Here’s how:
Good oral habits not only protect your fillings but also your entire mouth.
Tooth fillings are one of the most effective solutions for treating cavities and restoring dental health. From early detection to material selection and post-treatment care, understanding the entire process empowers you to make informed decisions for your smile.
