  • What factors does the durability of porcelain restoration depend on?

    In fact, the durability of porcelain teeth depends on many factors, not from "the material you choose on the price list". Those factors include:

    1️⃣ The durability of the real teeth that the porcelain restorations are put on:

    If your real teeth are weak or shaken after a period of use, which need to be pulled out, then porcelain restorations will also be gone!

    Real teeth are weak due to many reasons: root canal treatment, bone loss around the tooth making it loose, overloaded chewing force, etc. These factors need to be carefully evaluated by a doctor before treatment.

    This is the most common cause when assessing the durability of porcelain restorations after a few years of use.

    2️⃣ The tightness of porcelain restorations:

    Porcelain restorations that are attached but do not fit tightly will be exposed to the core of real teeth, after a while, saliva will dissolve the glue attached to the teeth, making the teeth sensitive, or causing tooth decay quickly (if patients already had root canal treatment).

    3️⃣ Invasive porcelain restorations cause gingivitis:

    If the porcelain restorations invade deep below the gums, the body will trigger a reaction that causes gingivitis. This part of gingivitis is complicated to treat, and it is usually necessary to remove the old porcelain restorations, surgically cut the gums and then make the porcelain restorations again.

    4️⃣ Porcelain restorations are too big, too thick, causing food stuffing:

    If porcelain teeth cause stuffing of food, it will cause difficulties in oral hygiene, and is a common cause of "bad breath after porcelain restorations".

    5️⃣ Porcelain restorations are too strong, causing breakage, affecting the opposite real teeth.

    Thus, it can be understood that making porcelain restorations is not simple. It is necessary to have a solid knowledge of tooth structure, understanding how to have a design that is suitable for chewing force, aesthetics, durability, to achieve satisfactory results for patients.
