Dental fillings · Greater Kailash 1, Delhi
A filling replaces the part of a tooth lost to decay or damage, after the decayed part has been cleaned out. At Orion Dental Clinic, a dentist in Greater Kailash 1 (GK 1), South Delhi, this page explains the types of filling, what systematic reviews say about how long each lasts, why fillings are replaced, and what can go wrong, in plain language, so that you can decide with confidence.
Treatment is planned by Dr Anupam Sinha (BDS, MDS) and Dr Natalia DeSilva (BDS, MDS). If you have a toothache now, call us. Ask as many questions as you need.
These figures come from systematic reviews, listed at the end of the page. Many of the trials are old, and materials have improved since. Your dentist will explain what suits your tooth.

Quick answer
Dental fillings at Orion Dental Clinic in Greater Kailash 1, Delhi repair a tooth after decay has been cleaned out, using composite, amalgam or glass ionomer. Dr Anupam Sinha and Dr Natalia DeSilva choose with you after an examination and X-rays. About 85 to 90 in 100 composite fillings lasted ten years in a large review.
01 Overview
A filling restores a tooth after decay, a chip or wear. The dentist numbs the tooth, removes the decayed part, cleans the cavity and fills it with a material that is shaped to the tooth and hardened, so that the tooth can be used again and the decay does not spread. Which material is used depends on the size and position of the cavity, how much of the tooth is left and what you prefer.
Three materials are common. Resin composite is tooth-coloured and is bonded to the tooth. Amalgam is the silver filling, which is still used in parts of the world. Glass ionomer and compomer are tooth-coloured materials that are used mostly in smaller cavities and in children.13 A fourth option, for larger repairs, is an inlay or a crown, which is covered on our page about dental crowns.
How long a filling lasts depends on the material, the size of the cavity, how well the tooth is cleaned and how you bite. In a review of 62 trials, resin composite fillings in back teeth survived at about 85% to 90% at 10 years, and glass-ionomer and compomer fillings at about 80% at 6 years.3 Fillings are replaced mainly because they fracture or wear, or because new decay forms at their edge.3
A filling is a repair that is expected to last for years, and not a promise that the tooth will never need work again.
02 Candidacy
A filling is advised when a tooth has a cavity, a chip or a worn area that can be repaired. The dentist decides after an examination and X-rays.
A filling treats the cavity, and the cause of the decay still has to be dealt with.
03 Options
The main choices are composite, amalgam and glass ionomer, and reviews give some comparisons.
Tooth-coloured fillings bonded to the tooth. In a review of 62 trials, about 85% to 90% were still in place at 10 years, and the main reasons for replacement were fracture and wear, then new decay at the edge.3
85% to 90% at 10 years 3
If a tooth needs more than a filling, ask about dental crowns. If decay has reached the pulp, see root canal treatment.
| Composite | Amalgam | Glass ionomer | |
|---|---|---|---|
| Appearance | Tooth-coloured | Silver | Tooth-coloured |
| What the reviews found | About 85% to 90% at 10 years 3 | Lower failure than composite in children's back teeth, low-certainty evidence 1 | About 80% at 6 years 3 |
| Main reasons for failure | Fracture and wear, then new decay at the edge 3 | Not different from composite for fracture, with less new decay at the edge 2 | Loss of shape, loss of contact and retention 3 |
The material affects how long a filling lasts, but the size of the cavity and your cleaning matter at least as much.
04 Procedure
Every case is individual, so your steps may differ. This is the usual order.13
A filling is quick, but the cleaning out of decay and the bite check decide how long it lasts.
The dentist asks about pain or sensitivity and examines the tooth, the gum and your bite. X-rays show decay between teeth or under old fillings.
You discuss composite, amalgam or glass ionomer for your tooth, with what the reviews found for each.13
A local anaesthetic is usually given, so that you should not feel pain during the work.
The decayed part is removed and the cavity is cleaned. Decay left behind, or new decay at the edge, is a common reason for a filling to fail.3
The material is placed and shaped. For composite, a bonding adhesive is used first, and the material is hardened in layers with a light. The way the adhesive is applied did not change post-operative sensitivity in a review of 13 trials.4
The filling is polished and the bite is checked so that it is not too high, which can cause soreness or fracture.
Your regular check-ups include the fillings, because most failures are found by examination and X-rays before they cause pain.
05 Aftercare
Your dentist will give you written instructions, and those come first.
Your lip, tongue or cheek may stay numb for a few hours, so be careful not to bite them. Wait until the numbness goes before eating hot food.
The tooth may be sensitive to cold, heat or biting for a few days. In a review, the way the adhesive was applied made no difference to this.4 Tell your dentist if it is getting worse or if the bite feels high.
Brush twice a day with fluoride toothpaste and clean between the teeth every day, especially at the edge of the filling, where new decay tends to form.3
Keep your regular check-ups so that wear, fracture or new decay at a filling is found early.
Call the clinic on 098115 01995 the same day if the pain gets worse instead of better, if the tooth throbs or keeps you awake, if swelling develops or spreads, if a piece of the filling or the tooth breaks off, or if your bite feels high. If you have trouble breathing or swallowing, or swelling that spreads across your face or neck, call 112 or go to a hospital emergency department.
Some sensitivity is normal, and pain that grows should be checked.
06 Limits and risks
A filling is the simplest repair, but it does not suit every tooth. These are situations where a different plan may be better:
In these cases root canal treatment, a crown or taking the tooth out may be better than a filling.
Fillings fail over time. In a review of 62 trials, composite fillings dropped to about 85% to 90% survival at 10 years, and about 70% of replacements were for fracture or wear, with about 20% for new decay at the edge.3
New decay at the edge. In trials in children's back teeth, composite fillings had a much higher risk of new decay than amalgam, with almost double the risk of failure overall, but the evidence was low-certainty and the materials have improved since.1 Another review found new decay to be a rare event in trials and the evidence on materials extremely scarce.5
Sensitivity. Post-operative sensitivity can happen after composite fillings, and the way the adhesive was applied made no difference in a review of 13 trials.4
Safety of materials. A Cochrane review found very low-certainty evidence of no clinically important difference in safety between amalgam and composite, and notes the global phase-down of amalgam.1 Ask your dentist which material is used and why.
A good plan names these limits before treatment starts, and treats a filling as a repair to be checked.
07 Your visit
At your first visit, a dentist at Orion Dental Clinic asks about any pain or sensitivity, what sets it off and how long it has been there. You are asked about your health, medicines and allergies, including any allergy to a dental material.
The dentist examines your teeth and gums and takes X-rays where needed. You then talk through whether a filling is the right repair, which materials are possible, what each would involve and what the limits are, and you can ask any question before work starts. If you are in pain, say so and we will see you as soon as we can.
The first visit is to find out what is wrong and what repair suits the tooth, and treatment can often start on the same day.

11 Travelling patients
A filling is usually a single visit, which makes it one of the easiest treatments to fit into a stay. Even so, the dentist needs to examine the tooth and take an X-ray first, so allow time for that, and tell us if you have pain now. We will give you your X-rays and a note for your own dentist at home.

A filling can fit a short stay, as long as the examination comes first.
12 Questions
A material placed in a tooth after decay or damage has been cleaned out, shaped to the tooth and hardened, so that the tooth can be used again.
In a review of 62 trials, about 85% to 90% of composite fillings in back teeth were still in place at 10 years, and about 80% of glass-ionomer and compomer fillings at 6 years.3
Mainly bulk fracture and wear, which accounted for about 70% of replacements of composite fillings, and new decay at the edge, which accounted for about 20%.3
A local anaesthetic is usually given, so you should not feel pain during the work. The tooth may be sensitive afterwards, and in a review the way the adhesive was applied made no difference to that.4
Yes. Fillings are replaced when they fracture, wear or develop new decay, and your regular check-ups are how this is found early.3
If decay has reached the pulp, the tooth may need root canal treatment, and if the tooth has little structure left, a crown may be better, and your dentist will explain which applies to your tooth.
