Teeth Whitening Guide (lookism guide)

[ikacsai]

Teeth whitening is a simple process, that can be complicated because of too much information. This topic will be about the strongest, typical form of at-home teeth whitening. The strongest form of at-home whitening is a gel whitening system(either either Carbamide Peroxide or Hydrogen Peroxide).

Carbamide Peroxide vs Hydrogen Peroxide

Carbamide Peroxide
Carbamide Peroxide is the most popular of the whitening systems. It is also the weaker of the two at a given % strength. It is the safer and less painful of the two. But it is similarly less effective at whitening. In general, I would suggest you start with Carbamide Peroxide, first. I would hold off on Hydrogen Peroxide unless you find that you don't respond to Carbamide Peroxide.

Carbamide Peroxide comes in strengths ranging from 5%-44%. I would strongly suggest starting in the 20% range. Nearly all people can tolerate that strength without too much pain. I would only buy the 10% if you try the 20% and find your teeth are just too sensitive. The 35% and 44% versions are quite strong. I would not suggest starting with these. You may want to consider them after your first treatment, if you didn't get your teeth as white as you wanted.

Hydrogen Peroxide
Hydrogen Peroxide is by far the most powerful of the two. This stuff is so strong that if you leave it open next to 2Chainz bed, he'll look like Macklemore by the morning.

It is 3x as powerful % to % as Carbamide Peroxide. This stuff is effective. Almost anyone can get teeth in the range of A3-A4 when using this at high strengths. However, it comes with downsides that you should consider. The most important is the potential to damage enamel. It's not uncommon for someone using high strength Hydrogen Peroxide to do permanent damage to their enamel. This stuff is strong, so be careful with it!

Hydrogen Peroxide at 12% is similar to Carbamide Peroxide at 35%. Unfortunately, I have never seen legit Hydrogen Peroxide sold above 12% strength. Does that mean that you should never use it? I would only suggest it if you've tried at least 35% Carbamide Peroxide and still want better results. While it's strength equivalent, it isn't the same. It works a lot faster, and it is also stronger when paired with an LED light. I'd consider it a last resort, but I would suggest trying it, if you've used 44% Carbamide Peroxide and still need something more(this will be less than 10% of you).

Other supplies
You will need trays to put the gel in. You will also need remineralizing gel. It will be used after every treatment(you also put it in the tray after washing it). You may consider getting cotton makeup pads, and placing one under your tongue when you use the trays to soak up saliva.

The session
Your session time is important to your success. If you don't use the gel for at least 20 minutes, your results will be poor. But if you use it more than an hour, you're basically spinning your wheels. It's a waste of time and is not more effective than an hour.
The optimal time is one hour of whitening

After Whitening
After every single whitening session, I'd suggest using remineralizing gel. The process of bleaching is harsh on your teeth and they can become dry if not treated. It also reduces pain felt in the coming days after a treatment.

Length of whitening cycle
You should whiten your teeth every single day, with no rest days for 14 days total. There have been studies on this, and it is the most effective way. Doing EoD or longer than 14 days is not optimal.
Daily treatment for 14 days offers 90% of the total results of a cycle vs 42 days

Months rest before next cycle
Your teeth need months to recover. You must wait at least 6 months between treatments. Failure to wait can result in enamel damage, and even lessen the effectiveness of the whitening treatment.

A good summary of several studies using just 10% Carbamide Peroxide

Swift et al. [8] found that patients who used 10% carbamide peroxide gel nightly for 2 weeks showed a 7 unit improvement (Vita Lumin shade guide) that decreased with 28% after 6 months which is quite similar to the 27% decrease found for Nite White ACP in this study (Figure 4). Leonard et al. [9] revealed that the whitening effect caused by 10% carbamide (Nite White Classic; 8–10 h/d for 14 days; A3 or darker) reported 5 units lighter teeth after 3.8 years. In three different articles [26–28] on 10% (C1 or darker teeth) carbamide peroxide which was applied for 2 h/day for 3 weeks, a value of 4.1 was reported one week after treatment, a value of 3.8 after 6 months and a value of 4.3 after one year. From these values, it can be deduced that there was no color relapse even after a one-year period which is in contrast to this study (Figures 1–4). In another study [7] where Opalescence PF 10% was also used overnight, but in contrast to this study applied for 21 days the lightness first increased with 3 units from A2 to A1 with no relapse after 21 days, 30 days, or 180 days. Again the no relapse is in contrast to this study. A study on a 10% carbamide peroxide whitener [25] on A2 or darker teeth when treated overnight (8 hours) for two weeks showed a = 6.57 after treatment with a 24% relapse after a 3-month period.

In contrast to our study, Ishikawa-Nagai et al. [19] reported a total higher tooth whitening effect (applied to darker than A2 teeth for 14 days at least for 4 hours daily) for Nite White Excel (5.84) than for Opalescence PF 10% (5.03), while we found no difference between the two but a quite similar value for Opalescence (5.20).

In a recent study [12] on Opalescence PF a much lower total increase of 3.66 was reported in contrast to the 5.2 (Figure 4) found in this study. This difference is most probably due to the color selection of the teeth to be treated. When darker teeth (A2 or darker) were selected for the experiment, the whitening effect was found to be higher (5.2; in this study) than when all teeth were included (3.66). Ritter et al. [10] (treated 6 weeks for about 7 h/day) stated that a 10% carbamide peroxide solution provided patients with aesthetic results up to 12 years post-bleach, while Swift et al. [8] concluded that a 10% carbamide peroxide still had satisfactory results 2 years postbleaching. In a study on 10% carbamide peroxide, it was reported that the whitening effect remained similar after a 6-month period, although the treatment period was different 2 h/day for 3 weeks [26]. Goo et al. [29] () (applied 2 weeks for 6 h/day) also found 10% carbamide peroxide effective with a linear increase in the whiteness as the period of treatment increased, while Deliperi and Bardwell [30] reported no decrease of the shade after a 2-year followup with 10% carbamide peroxide.
