Some patients may require a dental implant fitted with a crown instead of an inlay/onlay, if the cavity is too large for the treatment to be effective.

Patients will required to do a set of X-rays in order to ensure the health of the tooth’s structure. If the tooth’s roots are damaged or infected, root canal treatment will be necessary before the inlay/onlay procedure can begin.
How It Is Performed
The dentist will inject anaesthesia into the patient’s gum, in order to avoid any potential pain and discomfort during the procedure. The decayed parts of the tooth are then removed and space is created for the new inlay/onlay. An impression of the patient’s teeth is taken and sent to a dental technician which will create the inlay or onlay. A temporary inlay or filling is placed in the newly created space, in order to protect it from any decay. The patient will have to return in about a week to have the permanent inlay/onlay placed. Once the dentist receives the inlay/onlay from the dental technician, the provisory filling is removed and the permanent inlay/onlay is cemented into place. The tooth will then be polished, making the restoration less visible.
Patients will have to be a bit careful with their restored tooth for a few days after undergoing the procedure, and avoid putting too much pressure on it, giving the dental cement enough time to harden properly. Most patients will experience slight discomfort and pain, as well as an increase in teeth sensitivity for a week or two after undergoing the treatment. These post-treatment effects can be dealt with by using desensitizing tooth paste and light painkillers.
● Tooth cracking during the cleaning process ● Removing too much material from the tooth
● Secondary caries ● Tooth fractures
Inlay/onlay side effects can include: ● Sensitive teeth ● Discomfort ● Pain
The average inlay/onlay success rate is 96.1% at 10 years after the procedure, 87% at 20 years and 73.5% at 30 years after the procedure.
Before And After
When properly performed and cared for, inlays and onlays can last a lifetime, just as dental crowns would.
– Inlay vs onlay – What is the difference? Both are indirect restoration procedures. They are very similar, the only difference being that an onlay also replaces the tooth cusp, the elevated part of the tooth. – Are there any alternatives to inlays or onlays? Dental crowns are actually a type of onlay – crowns cover all of the surface of the tooth. – Is it painful? Not at all, discomfort is comparable to that of a normal filling.
