Who wouldn’t want a brilliantly white smile! Various factors can cause teeth to darken over time. Additionally, tooth discoloration may arise genetically. Even with a regular brushing routine, this does not always keep teeth white. This situation, which negatively affects self-confidence and sometimes prevents us from smiling, is resolved by teeth whitening treatments.
Reasons for Changes in Tooth Color
The causes of tooth color variations differ from person to person. Color changes may stem from intrinsic or extrinsic sources. Physiological factors, discolorations following amalgam fillings, stains resulting from antibiotic use during pregnancy or childhood, root canal treatments, excessive consumption of coffee, tea, and tobacco, or trauma-induced intrinsic discolorations all invite tooth yellowing.
Teeth Whitening Methods
1. In-Office Teeth Whitening Method
In-office teeth whitening is one of the most effective methods. During the examination, whitening agents with very high peroxide levels are used, so the teeth whiten more quickly and the effect lasts longer. Before the procedure, to achieve a more effective result, the patient should undergo a dental prophylaxis (tartar/stone removal). Photos are taken before and after the procedure for comparison. The in-office whitening procedure is usually completed in 2 or 3 sessions, though the number of sessions varies according to the degree of discoloration.
Before application, the dentist places a protective barrier to prevent damage to the gums. Then whitening gel is applied 2 or 3 times in 15-minute intervals. During the course of sessions, patients should minimize consumption of staining substances such as tea, coffee, and cigarettes. This operation may cause tooth sensitivity, but this sensitivity can be easily relieved with special toothpaste provided by the dentist.
2. At-Home Teeth Whitening Method
In at-home whitening, impressions are taken from the patient before the application. A transparent tray is fabricated based on these impressions. This method uses whitening agents with lower concentrations of carbamide peroxide compared to in-office treatments, so its effect is less long-lasting. The transparent trays and whitening agents are provided to the patient, and the dentist instructs the patient on how to use them. It is important to follow the dentist’s recommendations. The prepared agent is applied by the patient twice daily for two weeks. During this period, the dentist will request routine check-ups. The treatment procedure should be decided jointly by the dentist and patient.
3. Combined (Office + Home) Teeth Whitening Method
The combined whitening method involves applying both in-office and at-home whitening procedures together. After the in-office whitening session at the clinic, the patient continues the process at home.
4. Internal (Inside-Out) Teeth Whitening Method
This method is generally preferred for teeth that have changed color after a root canal treatment. First, existing fillings are removed from the tooth. Then whitening gel is placed into the resulting cavity, and the area is sealed with a temporary filling. In internal whitening, this application is repeated every three days until the desired tooth shade is achieved.
Duration of Effect of Whitening Methods
Although the longevity of the effect varies by patient, typically whitening effects last between 3 months and 4 years. If consumption of staining substances such as coffee, tea, and cigarettes is high, the whiteness will not last long. Its lifespan is much shorter in such cases. However, in individuals who avoid these substances, the whitening tends to be more durable. To maintain the effect longer, such aesthetic procedures should be repeated every 6 months. With regular check-ups, the duration of whitening effects is extended.
Are Whitening Methods Harmful?
Whitening procedures sometimes cause tooth sensitivity. This sensitivity usually relates to exposure to air or ingestion of very cold or hot foods. However, this should not alarm you. Tooth sensitivity after whitening is a common, expected side effect and typically subsides within 2 days. If it does not resolve within that period, you should consult your dentist. Whitening procedures conducted under dentist supervision have no inherent harm.
Who Is a Suitable Candidate for Whitening Methods?
Whitening can be performed on individuals over 18 whose tooth development is complete. In all cases, the treatment method recommended by a specialist dentist should be adopted. For example, patients with cavities or other dental issues must first have those problems treated, and only then proceed to whitening. If you have porcelain crowns, permanent whitening will not be effective. Therefore, whitening yields positive results only on healthy, natural teeth.
Do Whitening Procedures Hurt?
Under expert supervision, whitening procedures do not cause significant pain or soreness. Mild sensitivity after such aesthetic procedures is expected but does not adversely affect daily life. However, if there was preexisting decay or damaged enamel and whitening is applied over those areas, severe pain and damage may follow. That is why whitening must always be performed under the control of a specialist dentist.
Preparations Before Whitening
Patients undergo a preparatory phase before the application, under dentist supervision. Before whitening, any condition in the teeth or gums that could negatively affect the procedure must be resolved. For example, patients with cavities must have the decay removed first. Gum issues should be treated, and tartar cleaned. If such problems are not addressed, whitening procedures may harm rather than benefit the patient, leading to undesirable results.
Post-Whitening Care
Beyond steps before and during application, there are rules to follow after whitening:
- For a few days after whitening, pay attention to dietary intake. Avoid foods containing strong colorants for at least 2–3 days.
- Likewise, avoid acidic foods and beverages for a while; these can exacerbate sensitivity, a side effect of the procedure.
- In the days following the procedure, do not brush teeth aggressively. Brush gently and carefully.
- After the procedure, if your dentist recommends using a whitening toothpaste, you may use it once daily starting one week after whitening. Continue your other brushing routines with a regular toothpaste.
- Use desensitizing toothpastes to alleviate any sensitivity in teeth or gums.
When whitening procedures are followed under dentist guidance, successful results are achieved without pain. For any questions about the procedure, contact Dentakay.
