Tooth Decay and Cavities: Stages, Diagnosis, Filling Options, and Costs in Gurugram
A cavity rarely appears overnight. Tooth decay develops in stages, and catching it early means simpler, more affordable treatment. If you have noticed a dark spot, a rough edge, or sensitivity while eating, this guide explains what is happening inside your tooth, how dentists diagnose cavities, and what filling options and costs look like for patients in Gurugram.
The Stages of Tooth Decay
Tooth decay progresses gradually as bacteria in plaque produce acids that wear away tooth structure. Understanding these stages helps explain why early treatment is easier and less expensive.
- Enamel demineralization: The earliest stage shows up as white or chalky spots on the tooth surface. At this point, decay may still be reversible with fluoride treatment and improved brushing habits.
- Enamel decay: Once the acid breaks through the enamel, a small cavity forms. This stage usually has no pain but is visible on an X-ray or during a routine check-up.
- Dentin decay: Decay reaches the softer dentin layer beneath the enamel, spreading faster and often causing sensitivity to sweets, hot, or cold food.
- Pulp involvement: If untreated, decay reaches the nerve and blood supply inside the tooth, leading to noticeable pain, swelling, or sensitivity that lingers. This stage may require root canal treatment rather than a simple filling.
- Abscess formation: In advanced cases, infection can spread beyond the tooth root, causing swelling, throbbing pain, or a bad taste. This needs urgent dental attention.
How Cavities Are Diagnosed
At Dentistaa, diagnosis usually involves a combination of the following:
- Visual examination: Your dentist checks for discoloration, rough patches, or visible holes in the tooth.
- Dental X-rays: These reveal decay between teeth or beneath old fillings that are not visible to the naked eye, and help assess how close the decay is to the nerve.
- Probing with dental instruments: A gentle check with a dental explorer helps confirm soft or sticky areas that indicate active decay.
- Sensitivity testing: Reaction to cold or air can help determine whether the nerve is involved.
Regular check-ups every six months allow small cavities to be caught before they cause pain, which usually means a simpler and shorter treatment.
Filling Options for Cavities
The right filling material depends on the size and location of the cavity, along with your budget and aesthetic preference.
Composite (Tooth-Colored) Fillings
These are made of a resin material that matches your natural tooth shade. They bond directly to the tooth, require less removal of healthy structure, and are commonly used for front and back teeth alike.
Glass Ionomer Cement (GIC)
GIC releases fluoride and is often used for small cavities, in children's teeth, or below the gum line where moisture control is harder to manage.
Silver Amalgam Fillings
A traditional, durable option for back teeth. It is less commonly chosen today due to its metallic appearance, but it remains a strong and cost-effective choice in certain cases.
Inlays and Onlays
For larger cavities where a standard filling is not strong enough but a root canal is not needed, inlays or onlays made of composite or ceramic can restore the tooth while preserving more natural structure than a crown.
Typical Costs of Cavity Treatment in Gurugram
Costs vary depending on the size of the cavity, the material used, and whether additional steps like a root canal are needed. Below is a general guide for Gurugram; your dentist will confirm exact pricing after examination and X-rays.
| Treatment | Typical Range (INR) |
|---|---|
| Consultation and X-ray | Rs 300 to Rs 900 |
| Composite (tooth-colored) filling | Rs 1,000 to Rs 3,500 per tooth |
| Glass ionomer filling | Rs 800 to Rs 2,000 per tooth |
| Silver amalgam filling | Rs 600 to Rs 1,500 per tooth |
| Inlay or onlay | Rs 4,000 to Rs 9,000 per tooth |
These are typical ranges only and may vary based on individual case complexity. Your dentist at Dentistaa will provide a clear estimate after assessing your tooth.
Why Early Treatment Matters
A cavity treated in its early stages usually needs only a simple filling. Left untreated, it can progress to needing root canal treatment or even extraction, both of which involve more time, cost, and recovery. If you have noticed sensitivity, a visible spot, or discomfort while chewing, it is worth getting it checked sooner rather than later.

Frequently asked questions
Can a cavity heal on its own without a filling?
Very early decay affecting only the outer enamel can sometimes be reversed with fluoride and better oral hygiene. Once decay reaches the dentin layer, it cannot heal on its own and needs a filling to stop it from progressing.
How do I know if I need a filling or a root canal?
Your dentist checks this with an examination and an X-ray. If decay is limited to the tooth structure and has not reached the nerve, a filling is usually enough. If the nerve is infected or badly inflamed, root canal treatment is recommended.
Do cavity fillings hurt?
Most fillings are done under local anesthesia, so the procedure itself is not painful. You may feel mild sensitivity to hot or cold for a day or two afterward, which usually settles on its own.
How long do tooth-colored fillings last?
With good oral hygiene and regular check-ups, composite fillings typically last several years, often five to ten, depending on the size of the filling and how well you care for your teeth.
