they would work on any teeth. but it could harm their sensitive gums or they could swollow the solution on the strip... not a good idea....
Crest White is good for soothing gums, but only in moderation.
Honestly, I would just use it once a day because that is what I did before and it worked AMAZINGLY, but if you use it twice a day like I tried yesterday, I noticed that my teeth/gums are a little sensitive now....I'd say just go with once a day.
In order to fabricate dental whitening trays, to absolutely need to take an impression of your teeth, with a very stable and precise material, and then cast the impression and use it to make the trays. Only a dental professional can make those trays. By cyberanto
I would suggest going to the dentist. Those white strips can cause further irritation. They aren't recommended for people with gum or other oral issues.
Actually, you should! Unless otherwise stated on the box, all of the whitening gels and strips that I know of you do in order to give the bleaching agent direct access to the enamel on your teeth allowing it to be the most effective. Below is a link for more information on bleaching gels.
Anyone can use it, as long as they have their adult teeth grown out. However, using whitening strips can cause sensitivity to the teeth, and sometimes to the gums as well. It can also create gum irritation. As long as you're aware and fine with some of the side effects that might occur, you should be able to put it on. However, you should go to a dentist first, and see what she/he tells you. There may be a specific whitening strip for your type of teeth, or they can tell you precisely whether or not it's good for your teeth to put whitening strips. In addition, there are other ways to whiten teeth. Fruits, such as starfruit can help in whitening teeth, brushing your teeth everyday, and I also heard that putting baking soda with your toothpaste works as well. On the other hand, again, for precise ways to whiten your teeth the fastest and safely, it's recommended to ask your dentist first.
Not nearly as well. The active ingredient is hydrogen peroxide. It degrades to water and oxygen over time. After expiration, there is still active ingredient, but, depending on long they've been expired, the effect is diminished. http://www.3dwhite.com/teeth-whitening/3d-white-faq.aspx
There are many methods or tips to choose from such as teeth whitening strips, teeth whitening pens and teeth whitening gel. You can also avoid or lessen your consumption of any dark colored beverages like coffee, tea and sodas. Another option, if cost is a factor, is to rinse with Hydrogen peroxide and follow with your brush dipped in baking soda with tooth paste. Peroxide can be used as an oral rinse, but follow the instructions on the bottle label for the dilution ratio. In addition to its whitening properties, peroxide oxygenates which kills anaerobic bacteria. You'll end up with whiter teeth, healthier gums and fresher breath.
Hydrogen peroxide is a bleaching agent that can react with the pigments in your gums, leading to a temporary whitening effect. However, it can also cause irritation and damage to the sensitive gum tissues if not used properly. It is important to use hydrogen peroxide solutions in recommended concentrations and not to leave it in contact with your gums for too long.
Gums may turn white because there is a lack of blood flow. This can cause numbness as well. Gums can also turn white due to gum disease.
Teeth whitening products might often contain harsh chemicals(Peroxide) that can be harmful to gums if you are not careful. Most dental offices are professionals and are more careful when performing this task.
