365 Boston Dental Clinic
Hello, this is 365 Boston Dental.
During consultations at 365 Boston Dental in Sinchon, Seodaemun-gu, we often hear patients ask, "Doesn't Teeth whitening make teeth weaker?" or "I've heard that teeth get damaged after whitening; is that okay?"
Many people worry that Teeth whitening is a treatment that damages teeth, but in our practice, we prioritize thoroughly checking the current condition of the teeth and gums to evaluate whether whitening is appropriate before proceeding. This is because the cause of tooth discoloration and the oral condition vary for every patient, so the treatment plan can also differ.
Is it true that Teeth whitening damages teeth?
It is important to first identify the cause if you have tooth sensitivity or discomfort. Not every patient undergoes Teeth whitening under the same conditions; we determine if whitening is appropriate after a comprehensive evaluation of the current state of the teeth and gums. It is crucial to establish a treatment plan tailored to the patient through this process.
✅ Identify the cause of tooth discoloration.
✅ Evaluate dental caries or gum condition together.
✅ Check for symptoms of tooth sensitivity or discomfort.
✅ Review if the current tooth condition is suitable for Teeth whitening.
✅ Provide an appropriate treatment plan based on the examination results.
Rather than judging based solely on the rumor that "teeth get damaged," it is important to fully check the current oral condition and evaluate the feasibility of the treatment. Establishing a suitable treatment plan through sufficient consultation and precise diagnosis can be the first step toward a highly satisfying Teeth whitening.
Things to check before Teeth whitening
As mentioned earlier, Teeth whitening is not a treatment that is performed immediately; it is important to plan it after thoroughly checking the current condition of the teeth. Even with the same tooth discoloration, the cause and oral condition can differ from person to person, so we look at what needs to be checked first before starting treatment.
In the clinic, we check for dental caries, gum condition, and the presence of existing prosthetics. Areas that have already undergone restorative treatment, such as crowns or resins, may not change color with Teeth whitening, so we explain this in advance while setting up the treatment plan.
We also check if there is a difference between the tooth color the patient expects and the current tooth condition. Since Teeth whitening is a treatment planned based on the current state of the teeth, it is important to understand the possible range and direction of treatment through sufficient consultation before treatment.
✅ Check the cause of tooth discoloration and current tooth color.
✅ Evaluate dental caries or gum health together.
✅ Check the condition of existing prosthetics such as crowns or resins.
✅ Review if the current tooth condition is suitable for Teeth whitening.
✅ Consult sufficiently on treatment goals and expected processes.
As such, Teeth whitening should not only be a process of making teeth white, but also a process of accurately grasping the current oral condition and setting up a treatment plan. It is important to decide on a treatment direction that fits the current state based on sufficient diagnosis and consultation.
When is Teeth whitening difficult?
The treatment direction may vary depending on the cause of tooth discoloration and the current oral condition, and in some cases, there may be treatments that need to be checked or performed prior to Teeth whitening.
The feasibility of Teeth whitening is not judged solely by looking at the color of the teeth. We guide the treatment direction suitable for the current state after comprehensively checking the current teeth and gum condition, existing prosthetics, and the cause of discoloration.
✅ Cases where dental caries or gum health need to be checked first.
✅ Cases where there are existing prosthetics such as crowns or resins.
✅ Cases where internal tooth discoloration needs to be checked.
✅ Cases where there is tooth sensitivity or other discomfort.
✅ Cases where the cause of tooth color change needs to be checked first.
As such, Teeth whitening is not a treatment applied equally in all cases. Analyzing the current state of the teeth and the cause of discoloration sufficiently and then setting up a suitable treatment plan can be an important process for planning a highly satisfying Teeth whitening.
