  What’s the best at-home Teeth Whitening Kit?

  RDH here. Most people think it’s extrinsic - coffee but it’s just that you never had white teeth or you’ve gotten older. The dentin inside teeth darkens with age. Whitening toothpastes do not change the color - they only help with smoking 🚬 stain and that’s another dental issue. You can try crest white strips. Never worked for me, but made my bro in law brilliant white. I prefer the Sheer White just because they stick better and don’t taste gross. Another brand that used to be dds only is opalesance and they’ve got a tray pack that is good

  The Best Teeth Whitening Recommended to Buy?

  This is the way. Dental hygienist here! The trays that your dentist custom makes for you are more effective, cheaper in the long run, and will last years (as long as you take care of them). And OP is 100% correct, stronger than what you can get over the counter (OTC) and safer (since the trays are fitted for your teeth and the whitening gels won’t spread all over your gums). From the list above, if you have to go OTC, Opalescence Go trays are the best. Start with a low percentage and work your way up. The best advice I have for whitening is to be super consistent (either every other day or daily). The whitening solution has to create micropores in your enamel to whiten the structure underneath (dentin). If you are experiencing sensitivity, which you will, use something like Sensodyne or whiten less frequently.

  Dentist here- custom trays and gel tubes are the ultimate BIFL. The trays will last you forever unless you lose all your teeth or undergo orthodontics. Boring but important facts: Carbamide peroxide and hydrogen peroxide are the only chemicals that are going to whiten your teeth effectively and safely. Carbamide peroxide breaks down into hydrogen peroxide slowly and will work for longer, plus it is more gentle as hydrogen peroxide can cause more sensitivity. Carbamide peroxide also has a longer shelf life although both can be refrigerated to help them last longer. Crest white strips have a much lower concentration of peroxide than the gel tubes or prefilled Opalescence Go trays so they work but will take longer. Neither of the prefilled trays allow for you to place the whitening agent exactly where to want it which is overkill. Prefilled trays are better than the strips because they’re made to be a little smaller than the Crest strips, but they’re more expensive and leave a lot of plastic waste. Custom trays in my opinion are the best overall as you can add gel to only the teeth that are visible in your smile, you can choose Carbamide peroxide or hydrogen peroxide gel (available on Amazon), and overtime the tubes of gel are cheaper than anything else. All of the rest of the options are gimmicky: LED lights do not work, they just appear to make the teeth whiter by drying them out temporarily, charcoal does more harm because it is abrasive to enamel and will cause scratches that will get more surface staining over time, and pens and gels that just smear onto the teeth are just going to get come off of the teeth and get swallowed if there is nothing to hold them in place like a tray. Last: everyone’s teeth are going to whiten differently so comparing one persons use of white strips to another persons use of gel isn’t a good comparison as there are many factors that determine the colors of your teeth. The only way to compare products is to try them all yourself.

  Great question—I've tried a few of these! Crest 3D Whitestrips gave me noticeable results in a week, but I had to use a sensitivity toothpaste alongside them. Opalescence Go trays were more comfortable and less harsh, though a bit pricier. If you're prone to sensitivity, Lumineux (which uses natural ingredients) might be gentler, though results are slower. Pro tip: always brush with a fluoride toothpaste before whitening and avoid acidic foods right after to help protect your enamel.

  I think Opalescence Go prefilled trays are very good. It can be recommended. I think it will provide good result.

  I asked my dentist and they didn’t actually recommend in house whitening. They recommended opalescence- which they also sold. I haven’t had terrible sensitivity with them, and I’m on tray 4. It’s a series of 10. I do see a difference.

  The Best Teeth Whitening to Buy that Works?

  Dentist here as well. Use a baking soda based tooth paste once every couple days to remove dark stains from wine or coffee. Whitening won’t get rid of stains but will lighten a tooth’s overall color from yellow to white. Crest white strips or opalescence to go both do a great job taking a darker yellow colored tooth to a lighter shade.

  The Best Teeth Whitening to Buy that Works?

  Dentist here. Depends on degree of staining. Make sure you have had a professional cleaning or maintenance in the last 6 months. Additionally this is not really a buy it for life situation. If you keep chewing espresso beans and gargling with Merlot you will see limited results, if any. A likely starting point is Crest Whitestrips and in particular a sensitivity one. You can try to leave something like Sensodyne on your teeth for 20 minutes before and after. The active ingredient is potassium nitrate (really). Much easier with carrier trays or even clear aligners or retainers. A step up would be Opalescence Go trays which you can get on Amazon, but you will likely experience more sensitivity. If it’s really bad and you really want to change it in a professional setting, talk to your provider.
