Saving more of your natural tooth is always the better option. Inlays and onlays make that possible.
When a cavity is too large for a standard filling but the tooth does not need a full crown, an inlay or onlay is the smart middle ground. These lab-crafted restorations fit precisely into the prepared tooth, preserve more natural structure than a crown, and last significantly longer than large direct fillings. Thailand's dental clinics fabricate them from premium ceramics at prices that make the trip worthwhile.
Free, no-obligation — you pay the hospital directly with no markup.
An inlay fills a cavity within the cusps of a back tooth. An onlay extends further, covering one or more cusps for larger areas of damage. Both are fabricated in a lab from porcelain, composite, or gold, then bonded into the prepared tooth with adhesive resin cement.
The practical advantage over large direct fillings is durability. A big composite filling weakens over time, shrinks during curing, and is prone to cracking. A lab-made inlay or onlay does not shrink, distributes force more evenly, and can last twice as long. The advantage over a crown is conservation — you keep more of your own tooth intact.
Inlay and onlay work in Thailand costs a fraction of what you would pay at home, which makes it practical to replace old amalgam fillings across multiple teeth in a single trip.
Conservative
More Tooth Preserved
Inlays and onlays remove only damaged material and leave healthy tooth structure intact. Our partner dentists take a conservative-first approach, recommending crowns only when genuinely necessary.

We do not charge for our service — you pay the clinic directly with no markup. Here is what inlays and onlays typically cost, what affects pricing, and how Thailand compares internationally.
Your Quote Will Include
Prices are approximate and vary by technique, surgeon, and hospital. Your personalised quote will include a full cost breakdown.
A single porcelain inlay or onlay in Thailand typically costs between $200 and $400. Composite restorations sit at the lower end, ceramic in the middle, and gold at the top. If you are replacing old amalgam fillings across several teeth, the total cost in Thailand is often less than a single restoration at home.
The total cost covers the dentist's fee for preparation and bonding, the laboratory fee for fabricating the restoration, digital scanning or impressions, and follow-up. The lab fee is the largest component, reflecting the material quality and the technician's skill in crafting a restoration that fits precisely.
Material is the main variable. Composite costs less, porcelain costs more, and gold is at the premium end. The size of the restoration also matters — an onlay covering multiple cusps uses more material and lab time than a small inlay. The number of restorations affects the overall quote, with per-unit costs often dropping when multiple teeth are treated in the same trip.

Exact pricing is confirmed after your consultation.
Inlays and onlays in Thailand cost 60–70% less than equivalent restorations in the US ($600–$1,200), Australia (A$550–A$1,100), and UK (£500–£1,000). The savings are driven by lower operating costs in Thailand, not by differences in material or clinical quality. Our partner clinics use the same ceramics and bonding systems as leading international practices.
The choice between inlay and onlay depends on how much tooth is damaged. The choice of material depends on where the tooth sits and how much force it takes.
Made from dental-grade lithium disilicate or leucite-reinforced ceramic. These restorations offer the closest match to natural enamel in colour, translucency, and surface texture. They are stain-resistant and hold their appearance over many years.
Lab-fabricated from tooth-coloured composite resin. Slightly more flexible than porcelain, which means less stress on the opposing tooth during chewing. Easier to repair if damaged and gentler on the bite contact. The trade-off is shorter lifespan compared to ceramic.
Cast from a gold alloy, these restorations have the longest clinical track record of any indirect filling material. Gold wears at a similar rate to natural enamel, meaning it does not damage opposing teeth. Aesthetics are the only downside — you trade appearance for maximum durability.
The fabrication method determines how well the restoration fits the tooth. Digital workflows produce measurably tighter margins than traditional techniques, and Thailand's top clinics have adopted them fully.
An intraoral scanner captures the prepared tooth digitally. The restoration is designed on screen and milled from a ceramic block or sent to a lab for pressing. This eliminates distortion from impression materials and produces margins accurate to within microns.
For straightforward cases, the inlay or onlay can be milled chairside during a single appointment. The dentist scans, designs, and mills the restoration in about an hour. Useful when time is limited, though lab-finished restorations offer more aesthetic refinement.
A physical impression is sent to a dental laboratory where a technician hand-crafts the restoration. This route allows hand-staining and glazing for superior colour matching on visible teeth. Takes three to five working days but produces the most refined result.
Some sensitivity around the restored tooth is typical once the restoration is bonded. Local anaesthesia wears off within a few hours. Stick to soft foods and chew on the opposite side for comfort.
Sensitivity fades. You can resume normal eating, starting with softer foods and working up. Brush and floss as usual, paying attention to the restoration margins where food can collect.
The restoration should feel like part of your own tooth. At your follow-up, the fit, bite alignment, and surrounding gum health are all checked. Any minor adjustments are made before you travel home.
The tooth and surrounding tissue have settled fully. The bonded restoration functions without restriction. Regular brushing, flossing, and dental check-ups will maximise its lifespan.
You can fly home the same day the restoration is bonded. Inlays and onlays are non-surgical, so there are no wound-healing or cabin-pressure concerns. Most patients stay five to seven days to allow for lab fabrication and the fitting appointment, then fly home with the restoration complete.
You can eat normally within a few hours of the inlay or onlay being bonded. Mild sensitivity to temperature may last a day or two, which is typical as the tooth adjusts. Avoid extremely hard foods for the first 24 hours while the bonding agent reaches full strength.
Results are immediate. Once the inlay or onlay is bonded and polished, the restoration looks and functions like a natural part of the tooth. There is no swelling or healing period — what you see in the chair is the finished result.
Inlays and onlays are well-established indirect restorations with an excellent safety profile. Complications are rare when the procedure is performed by an experienced dentist with quality materials and proper bonding protocols.
Whether an inlay, onlay, or full crown is the right treatment is determined before preparation begins, using X-rays and clinical assessment. Choosing the most conservative option that still delivers a reliable, lasting result is always the goal.
Yes. Inlay and onlay placement is routine conservative dentistry. Our partner clinics in Thailand use the same ceramics, bonding agents, and digital scanning systems as top practices internationally. The dentists are qualified and experienced, and the infection-control protocols are rigorous.
Ensure the clinic uses digital scanning for impressions — the accuracy is measurably better than putty, which matters for restoration fit. Ask about the bonding protocol, specifically whether rubber dam isolation is used during cementation. Rubber dam keeps the bonding surface dry and dramatically improves bond strength and longevity.
Porcelain inlays and onlays typically last 10–15 years, and gold can exceed 20. Replacement is needed when there is decay at the margin, the restoration chips or fractures, or the bond fails and the restoration loosens. Regular check-ups catch these problems early. If an inlay or onlay does fail, it can usually be replaced without further weakening the tooth.
Precision is everything in inlay and onlay work. The dentist's preparation and the lab's fabrication must both be accurate to within fractions of a millimetre.
Our partner clinics operate with in-house digital labs, CAD/CAM milling, and dedicated ceramic technicians. They handle high volumes of conservative restorative work and are set up to produce inlays and onlays with consistently tight margins and accurate colour matching.
Our partner dentists hold accredited qualifications and many have advanced training in conservative and adhesive dentistry. The emphasis on tooth preservation — using an inlay rather than defaulting to a crown — reflects a clinical philosophy that aligns with current best practice globally.
Ask about bonding protocols, specifically whether rubber dam is used during cementation. Review before-and-after photos of inlay and onlay cases. Check whether the clinic uses digital scanning or conventional impressions. A dentist who recommends the most conservative restoration that addresses the problem, rather than over-treating with a full crown, is usually the one you want.
Inlay and onlay results are immediate after bonding. Here is what a realistic outcome looks like.
A well-crafted porcelain inlay or onlay is virtually impossible to distinguish from the surrounding tooth. The ceramic matches the enamel in colour, translucency, and surface sheen. From a functional standpoint, the tooth regains its original contour and bite contact. Old metal fillings are replaced with continuous, tooth-coloured restorations that look like they were never damaged.
The result is visible as soon as the restoration is bonded — there is no healing wait. The tooth looks and feels whole again. Ceramic restorations maintain their colour indefinitely, unlike composite fillings that can stain or yellow over time. Longevity depends on oral hygiene, the material selected, and avoiding habits like ice-chewing that place excessive stress on teeth.
Most inlay and onlay cases take five to seven days. Here is how to plan your trip and what to expect.
Plan for five to seven days. Day one covers consultation, X-rays, and tooth preparation. The lab fabricates your restorations over three to five days, during which a temporary filling protects the tooth. The second appointment bonds the permanent restoration and checks the fit. If you have multiple teeth, they are all prepared on the same day.
Your care coordinator schedules appointments, arranges clinic transfers, and handles communication. The treatment quote covers consultation, digital scans, tooth preparation, temporary filling, lab fabrication, bonding, and follow-up. Flights and accommodation are separate, but your coordinator can recommend convenient hotels near the clinic.
Inlay and onlay work requires no downtime. You can explore Bangkok between appointments and eat normally once the temporary filling is placed. The only restriction is avoiding hard or sticky foods on the treated side until the permanent restoration is bonded. Many patients combine inlay work with other treatments during the same trip.
