Find out how long a tooth gem can last, which factors really affect its hold, and how to explain this clearly to your clients.
A tooth gem does not last exactly the same amount of time in every case.
In general, people often speak about a hold that can range from a few weeks to several months, but this duration depends on several very concrete factors.
For a professional, the right approach is therefore not to announce one fixed duration to every client, but to explain that the hold varies depending on:
- the quality of the application;
- the placement of the jewel;
- the products used;
- the client’s habits;
- and the care taken in the hours and days following the application.
The first thing to understand: there is no single universal duration
A tooth gem does not always last the same amount of time, even when the same jewel is used.
Two applications can last for different periods simply because:
- the tooth is not exposed to the same stresses;
- the jewel is not placed in the same area;
- the client does not have the same habits;
- or the application was not carried out with exactly the same level of precision.
In other words, the hold should be presented as a variable duration, not as the same promise for everyone.
The quality of the application plays a central role
The hold depends first on the technical quality of the application.
If the preparation is done properly and the jewel is fixed correctly, the hold will naturally be more stable.
On the other hand, if the composite does not surround the jewel well enough, or if the fixation is not clean enough, the tooth gem may be more exposed and may not last as long.
This is therefore one of the first points to explain to a client: the durability depends to a large extent on the quality of the application.
The placement of the jewel has a major impact on durability
The placement of the tooth gem also plays a very important role.
If the jewel is placed too close to contact zones or to the edges of the tooth, it may be more exposed to friction during chewing.
For example:
- a jewel placed very close to the natural contours of the tooth may be subject to more friction;
- depending on the bite, the upper and lower teeth may also hit the gem more easily during chewing.
So even with a beautiful application, poor placement can reduce how long it lasts.
The products used also influence durability
The hold also depends on the quality of the products used during the application.
This notably includes:
- the composite;
- the etching gel;
- the primer;
- and, more broadly, the overall consistency of the fixation protocol.
So the durability of a tooth gem does not depend only on the jewel itself, but also on the entire preparation and fixation process.
Saliva acidity can also play a role
Some clients will naturally have a more favourable oral environment than others.
Saliva acidity can influence the hold over time, just like other characteristics specific to the client’s mouth.
This is useful to keep in mind, because it shows that even a technically well-done application may evolve differently depending on the person.
The client’s habits also affect how long it lasts
Even with a very good application, certain habits can reduce how long the tooth gem stays in place.
For example:
- repeated friction;
- impact during chewing;
- certain aggressive habits;
- bruxism;
- or frequent stress on the application area.
That is why the hold does not depend only on the professional, but also on the client’s daily habits.
The first few hours after application are important
Immediate aftercare also matters.
It is useful to recommend that the client:
- does not drink for the 2 to 3 hours following the application;
- does not smoke for the 2 to 3 hours following the application;
- avoids hot drinks for the 2 to 3 hours following the application;
- and more generally avoids putting unnecessary stress on the area right after the application.
These first precautions help the application settle under better conditions.
How should you explain the hold to a client?
The easiest way is to avoid promises that are too rigid.
Instead of saying that a tooth gem will always last exactly a certain number of weeks or months, it is more accurate to explain that:
- the hold can range from a few weeks to several months;
- but that it depends on placement, application quality, products, aftercare, and lifestyle habits.
This is a more professional, more realistic, and easier-to-defend answer if the hold varies from one client to another.
What about an application guarantee?
In practice, many professionals define a short guarantee period to frame the initial hold of the application.
The idea is not to guarantee a total duration over several months, but rather to cover the phase during which a possible application defect could appear.
The exact duration of this guarantee then depends on:
- your protocol;
- the way you work;
- your commercial policy;
- and the level of security you want to keep in your client communication.
The most important thing is that the duration you announce remains consistent with your actual practice and with what you are prepared to take responsibility for.
The simplest thing to remember as a professional
If you need to summarise the situation for a client, the most accurate logic is the following:
- a tooth gem can last from a few weeks to several months;
- the hold varies depending on the quality of the application;
- the placement of the jewel plays an important role;
- the oral environment and the client’s habits also influence the duration;
- and the first few hours after the application must be respected to give the application the best possible chance to last well.
Key takeaways
A tooth gem does not always last the same amount of time.
Its hold depends notably on:
- the quality of the application;
- the placement of the jewel;
- the quality of the composite, etching gel, and primer;
- the acidity of the saliva;
- the client’s habits;
- and respecting the advice given right after the application, such as not drinking, not smoking, and avoiding hot drinks for the 2 to 3 hours that follow.
The most accurate approach, for a professional, is therefore to speak about a variable hold, not a fixed duration guaranteed in every case.
