Cavity Fillings Explained: Materials, Procedure and Costs in Gurugram
A toothache or a dark spot on your tooth is usually your body telling you there is a cavity. Cavities are one of the most common dental problems we see at our clinic in Sector 48, Gurugram, and the good news is that treating them early with a simple filling is usually quick, affordable, and painless.
How Cavities Actually Form
Your mouth is full of bacteria. When you eat sugary or starchy foods, these bacteria produce acid as a byproduct. This acid slowly dissolves the hard outer layer of your tooth, called enamel. Over time, this creates a small hole, which is the cavity.
If left untreated, the decay does not stop at the enamel. It moves deeper into the dentin layer and can eventually reach the nerve inside the tooth, causing severe pain and sometimes requiring root canal treatment instead of a simple filling. This is why addressing a cavity early, while it is still small, saves you time, discomfort, and cost later.
Common Signs You Might Have a Cavity
- Sensitivity to hot, cold, or sweet foods
- A visible brown, black, or white spot on the tooth
- Pain when biting or chewing
- Food frequently getting stuck in one particular tooth
- Bad breath or an unpleasant taste that does not go away
Some cavities, especially between teeth, are not visible to the naked eye and are only caught during an X-ray at a routine dental checkup.
How Dentists Choose a Filling Material
There is no single best filling material for everyone. The choice depends on where the cavity is, how large it is, your bite pressure, your budget, and sometimes your aesthetic preference. Here is how we think through it.
Composite (Tooth Coloured) Filling
Composite resin is matched to your natural tooth shade, making it nearly invisible. It bonds directly to the tooth structure, which means less drilling is often needed compared to older materials. It works well for front teeth and small to medium cavities in back teeth. The main consideration is that it can wear down slightly faster than some other materials in very high bite-pressure areas.
Amalgam (Silver) Filling
This is a durable, time-tested material made of a metal alloy. It is strong and handles chewing pressure well, which makes it a reasonable option for large cavities in back molars where appearance matters less. Its main drawback is the metallic colour, which is visible when you open your mouth wide.
Glass Ionomer Cement (GIC)
GIC releases fluoride, which can help protect against further decay. It is often used for fillings in children's teeth, small cavities near the gumline, or as a temporary filling before a more permanent restoration.
Ceramic or Inlay Fillings
For larger cavities where a simple filling may not hold up well, a lab-made ceramic inlay or onlay might be recommended. These are stronger and more durable but usually need two visits and cost more than direct fillings.
| Material | Best For | Appearance |
|---|---|---|
| Composite | Front teeth, small-medium cavities | Tooth coloured |
| Amalgam | Large cavities, back molars | Silver/metallic |
| Glass Ionomer | Children, gumline cavities | Tooth coloured, less polished |
| Ceramic Inlay | Large cavities needing strength | Tooth coloured, highly polished |
What Happens During the Filling Procedure
- The dentist examines the tooth and may take an X-ray to check how deep the decay goes
- Local anaesthesia is given to numb the area around the tooth
- Decayed tissue is gently removed using a dental drill
- The cavity is cleaned and shaped to hold the filling material
- The chosen filling material is placed, shaped, and hardened, often using a curing light for composite
- The bite is checked and adjusted so the filling feels comfortable
Most filling appointments take between 20 and 45 minutes depending on the size and location of the cavity. You can usually eat normally once the numbness wears off, typically after a couple of hours.
Typical Cost of Fillings in Gurugram
Costs vary based on the material used, the size of the cavity, and whether any additional X-rays or treatment are needed. As a general guide, simple fillings in Gurugram fall in a typical range of a few thousand rupees, with composite fillings generally costing more than amalgam or glass ionomer due to the material and technique involved. Ceramic inlays sit at the higher end of the typical range because of the lab work involved. For an accurate quote specific to your tooth, an in-person examination is the only reliable way to know the exact cost.
Preventing Future Cavities
Brushing twice daily with fluoride toothpaste, flossing once a day, cutting down on sugary snacks between meals, and visiting your dentist every six months for a checkup can significantly reduce your risk of new cavities forming. Catching decay early almost always means simpler, more affordable treatment.

Frequently asked questions
How do I know if I have a cavity?
Common signs include tooth sensitivity to sweets or cold, a visible dark spot or hole, pain while chewing, or a dull ache. Some early cavities show no symptoms at all, which is why routine checkups matter.
Does getting a filling hurt?
Most patients feel little to no pain because the area is numbed with local anaesthesia before any drilling. You may feel slight pressure or vibration, but not sharp pain.
How long does a filling last?
With good oral hygiene, composite fillings typically last 5 to 7 years and amalgam fillings can last longer, sometimes over a decade. Lifespan depends on the size of the filling, your bite, and daily care.
Can a cavity heal on its own without a filling?
Very early enamel demineralisation can sometimes be reversed with fluoride and better hygiene, but once a cavity has formed a hole into the dentin, it will not heal on its own and needs a filling to stop it from spreading.
