Everything you need to know about tooth-coloured dental fillings in Hyderabad — the difference between composite and porcelain, when inlays and onlays are the better choice, how they compare to silver amalgam, and what to expect at Smilebook Dental.
What is the difference between composite and porcelain fillings in Hyderabad?
Composite fillings are tooth-coloured resin restorations placed directly in the tooth in a single appointment — ideal for small to medium cavities. Porcelain fillings (inlays and onlays) are ceramic restorations fabricated in a laboratory and bonded to the tooth — used for larger cavities where composite does not provide sufficient strength. At Smilebook Dental Hyderabad, porcelain inlays and onlays are fabricated in the in-house CAD/CAM lab. No silver amalgam fillings are used. Contact: +91 95159 61060.
Composite Fillings — What They Are and When They’re Used
What is a composite filling?
A composite filling is a tooth-coloured resin restoration placed directly into a prepared cavity in a single appointment. The dentist applies the composite resin in layers, shapes it to restore the natural tooth contour, then hardens each layer with a blue curing light. Composite fillings bond directly to the tooth surface — requiring less healthy tooth structure to be removed than amalgam — and are indistinguishable from natural tooth enamel when colour-matched correctly.
Composite fillings are the standard restorative option at Smilebook Dental for small to medium cavities in both front and back teeth. Because the resin bonds chemically and mechanically to the tooth surface, it reinforces the remaining tooth structure rather than simply filling the space — a significant advantage over amalgam, which relies on mechanical retention and does not bond to the tooth.
Porcelain Inlays and Onlays — When More Strength Is Needed
What is a dental inlay or onlay?
A dental inlay is a porcelain restoration that fills a cavity within the cusps of a back tooth — larger than a standard composite filling but smaller than a crown. An onlay extends over one or more of the tooth’s cusps, providing more coverage than an inlay. Both are fabricated in Smilebook’s in-house CAD/CAM lab from a digital impression and bonded permanently to the tooth. They bridge the clinical gap between a direct composite filling and a full porcelain crown.
Inlays and onlays are indicated when a cavity is too large for a direct composite filling to provide adequate strength and durability, but the remaining tooth structure is still sound enough that a full crown — which covers the entire tooth — would remove more healthy enamel than necessary. They represent a conservative, high-strength middle option between a filling and a crown.
Because inlays and onlays are fabricated in the lab from a digital impression of the prepared tooth, they achieve a fit precision that a direct composite filling cannot match. The ceramic material is also harder and more wear-resistant than composite resin, which is why porcelain inlays and onlays consistently outlast direct fillings in large posterior restorations.
Porcelain Inlay
Sits within the cusps of the tooth. Used for mid-sized cavities in premolars and molars where composite alone lacks sufficient strength. Fabricated in-house in 2–5 days.
Porcelain Onlay
Extends over one or more cusps. Used when significant cusp structure has been lost to decay or fracture. More conservative than a full crown — preserves more natural tooth.
Composite Inlay
A lab-fabricated composite resin inlay — combines the aesthetic properties of composite with the improved fit of a lab-fabricated restoration. Slightly less durable than ceramic.
e.max Ceramic
IPS e.max lithium disilicate inlays for anterior or high-aesthetic posterior restorations. The same material used for premium crowns and veneers — exceptional natural appearance.
Composite vs Porcelain vs Amalgam — Full Comparison
Are white fillings better than silver amalgam fillings?
White tooth-coloured fillings (composite and porcelain) are generally preferred over silver amalgam because they are metal-free, require less healthy tooth structure removal, bond directly to the tooth strengthening the remaining structure, and are completely invisible. Amalgam fillings are not offered at Smilebook Dental — only tooth-coloured restorations are used across all cavity sizes and locations.

The Filling Procedure — What to Expect at Smilebook Dental
Composite Filling — Single Appointment
For a composite filling, local anaesthesia is administered if needed (for deeper cavities). The decayed tissue is removed with a drill and the cavity is shaped. A bonding agent is applied to the tooth surface, then composite resin is placed in layers, each hardened with a blue LED curing light. The filling is shaped to restore the natural tooth contour and adjusted for correct bite contact. Total appointment time: 30–60 minutes per tooth.
Porcelain Inlay or Onlay — Two Appointments
The first appointment removes decay and prepares the cavity. A digital scan of the prepared tooth is taken and sent to the in-house CAD/CAM lab, where the inlay or onlay is designed and milled in 2–5 days. A temporary filling protects the tooth in the interim. At the second appointment, the temporary is removed and the permanent porcelain restoration is bonded permanently to the tooth. Total chairside time across both appointments: approximately 1 hour.
How Long Do Fillings Last — And What Affects Longevity?
The lifespan of a dental filling depends on material, cavity size, bite forces, oral hygiene, and diet. Composite fillings in posterior teeth typically last 7–12 years, with smaller anterior composite restorations lasting longer because they experience less bite force. Porcelain inlays and onlays consistently last 15–20 years because the ceramic material is harder and more wear-resistant than composite resin.

Porcelain & Composite Fillings Hyderabad — FAQs
What is the difference between composite and porcelain fillings in Hyderabad? Composite fillings — tooth-coloured resin, placed in one appointment, best for small to medium cavities. Porcelain inlays and onlays — lab-fabricated ceramic restorations, 2 appointments, best for larger cavities where composite alone lacks sufficient strength. Both bond to the tooth surface. No amalgam used at Smilebook Dental.
Are white fillings better than silver amalgam in Hyderabad? Yes, for most patients. White fillings (composite and porcelain) are metal-free, require less healthy tooth removal, bond to the tooth surface strengthening it, and are completely invisible.

How long do composite fillings last in Hyderabad? Composite fillings at Smilebook Dental typically last 7–12 years in posterior teeth and longer in anterior teeth.
