Inlays and onlays risks and recovery.
A well fitted inlay or onlay is a low risk restoration, but not a no risk one. Here is what can go wrong, what recovery really feels like, and the catch that is specific to having the work done abroad. We never name a clinic.

Is it risky, and how long to settle?
An inlay or onlay is a low risk restoration whose risks are broadly similar to a filling. You can usually eat normally once the numbness wears off the same day, and any mild sensitivity to hot and cold tends to settle within a few days. Most lasting problems trace to a poor fit or a high bite, not to the restoration itself.
Risks are real even when a procedure is low risk overall, and no result is guaranteed. Reviewed June 2026. This is general information, not a substitute for advice from a qualified dentist.
What can go wrong.
An inlay or onlay is a routine restoration and serious complications are uncommon. The risks below are real and worth understanding before you commit, especially if you plan to travel for the work.
Mild sensitivity to hot, cold, or pressure is common in the first few days and usually fades. Sensitivity that worsens or lasts beyond a couple of weeks should be checked, as it can signal a deeper problem.
If the restoration sits even slightly proud, it can cause ache, jaw discomfort, or pain on chewing. This is a quick adjustment in the chair, but only if you can get back to the dentist who fitted it.
Where the cavity was deep and close to the nerve, the tooth can stay sensitive or, less often, the nerve can become inflamed and later need root canal treatment. This risk follows the tooth, not the country.
A well bonded inlay or onlay rarely comes loose, but a poor bond, a damp field during cementing, or heavy grinding can let it lift, chip, or crack. Hard or sticky food in the first day or two adds avoidable strain.
If the edge is not sealed cleanly, bacteria can creep under the restoration over time. Good margins and good home cleaning are what keep an inlay or onlay lasting for years.
What recovery actually looks like.
First few hours
The local anaesthetic wears off over a few hours. Avoid chewing on that side until feeling returns so you do not bite your cheek or tongue.
Day 1 to 2
Stick to softer food and avoid very hot, cold, hard, or sticky items. Mild ache or sensitivity is normal and usually eases with everyday pain relief.
First week
Most sensitivity has settled. Brush gently around the tooth and keep up normal cleaning. If the bite feels high, ask for a quick adjustment.
Beyond two weeks
Lingering or worsening pain is not expected and should be reviewed, since it can point to the bite, the bond, or the nerve.
An inlay or onlay is often a two stage job, prep then fit, unless the clinic mills it on the day. A high bite or a debond is a five minute fix in the chair, but only if you are still in the country. Plan your stay around the fit and the bite check, not just the preparation.
Agree in writing who adjusts or replaces the restoration if there is a problem after you fly home, and over what period. Standard travel insurance rarely covers planned dental work or its follow up.
Understand the risks, then compare safely.
Send one brief and we route it to vetted clinics that set out the risks, the recovery, the visit schedule, and any follow up terms honestly and in writing. You compare tailored plans with no pressure.

The things everyone asks.
Are inlays and onlays risky?
They are a routine, low risk restoration with risks broadly similar to a filling. Serious complications are uncommon. The risks that remain, such as sensitivity, a high bite, or a debond, are real, so they are worth understanding first.
How long does recovery take?
There is little real downtime. You can usually eat once the numbness fades the same day, and mild sensitivity to hot and cold tends to settle within a few days. Favour softer food for a day or two.
Is some sensitivity normal afterwards?
Yes. Short lived sensitivity to temperature and pressure is common as the tooth settles. Sensitivity that gets worse or lasts beyond a couple of weeks should be reviewed by a dentist.
Could I still need a root canal later?
Occasionally. On a tooth where the cavity was deep and close to the nerve, the nerve can later become inflamed and need root canal treatment. This depends on the tooth rather than where the work was done.
What if there is a problem once I am home?
A high bite or a debond is a quick fix in the chair, but hard to arrange from another country. Agree the follow up and any guarantee in writing before you travel, and build the fit and bite check into your stay.
