Gum Light, 32 LED Red & Blue Light Gums Sensitive Support and Teeth Whitening Accelerator

It does what it's supposed to, and does it pretty well, though it only lasts a couple years before the battery starts to go and the coating starts to get icky and tacky. I'm now on my third one, use it daily (on the red+blue setting) and it keeps my gums healthy and happy. When I first buy one, the charge usually lasts for 5 days, then eventually it drops to 4 and finally 3... and then a while after that I get a new one.The cons: charging is kind of a pain, it seems to work best if I don't plug in the USB end of the cable all the way. It also blinks the entire time it's charging. You want to cover it up or put it someplace you won't see it, because the blue light WILL hurt your eyes, and not just in the "painful to look at and creates a huge yellow spot in your vision" way.Seriously, they should have it be red light only for charging, so you don't damage people's vision. At least you'll know when to charge it by the way it blinks instead of turning on when you try to use it, so you can check if you need to charge it by seeing if it turns on again after you use it. (Unfortunately, the blinking is also blue, so I hide the lit part behind one palm when doing this test so it doesn't hurt my eyes.)The other minor issue is that the instructions tell you to dry your mouth before using it. I don't do this because I can't - I salivate so much that just having the thing in my mouth at all will have it drenched in no time. So I have to carefully rinse off the in-the-mouth part after each use. I've considered using plastic wrap or something to cover it, but that'd be quite a pain as well, and at this point I've got some skill at moving it around under the faucet in such a way that the main body doesn't get wet, at least most of the time. Luckily, stray drops just make it turn on, but again, that's when you get searing blue light in your eyes followed by yellow spots.Seriously, I really wish they would make it work red-light-first, with blue light only on the second touch. If they did that and did red for charging too, the entire thing would be much safer because it'd be almost impossible to end up with the blue light in your eyes by accident. (Yes, I get that some people only want the blue light for tooth lightening purposes, but that doesn't mean you can't just have one tap for red, two for blue, and three for red+blue, or some other ordering. Just require more than one tap for blue, that's all I ask.)

I never take the time to leave reviews. But this product is life-changing!!! I have used this a total of four times and I’m already seeing a huge difference. The inflammation is going down. My gums are turning light pink again!!!! my teeth, feel stronger my mouth feels healthier! No pain or discomfort!! Going to the dentist is time consuming and expensive specially if you don’t take the first opinion. I’m so thankful I tried this!!!!

He sees me using it and decided he wanted to use it with me at bedtime afyer brushing his teeth. I'd give this a 5 star but the first one I received didn't charge right and died afyer the first use and wouldn't hold a charge afyer that. I ordered a new one e I've used it 3 times and it seems to be holding a charge just fine.

WARNING: Electrical Short Circuit Risk!The two magnetic pins used to charge this device are EXTREMELY dangerous!!!!In my experience, after disconnecting the device from the charger, I left the charger plugged in without considering the METAL stand it was resting on. Unfortunately, the two exposed magnetic pins were attracted to the metal stand, and because the charger was still powered, it caused a short circuit.This type of short circuit caused the cord to overheat and literally MELT into the metal stand. Luckily, while i was searching for another cord, I felt something extremely hot on my hand and saw that the charger head was slowly melting!!! If I hadn't caught this when I did, there's NO DOUBT that it absolutely would've caused a fire!! 1000%.The design of this charging mechanism poses a SERIOUS SAFETY RISK and should be used with great caution, but they really should not be used at all!Before this happened, I loved the product! It was extremely comfortable and lasted for over 3 years. The product itself is great, however it's not worth the safety risk. Unfortunately, this has a major CON that outweighs all the PROS.

Worked a few times and then stopped.

I’ve used it like 5 times so far. Like others have said, it’s sensitive to turn on, and the charger feels kind of flimsy. Other than that, the LEDs are bright and powerful, and provided they last awhile I think it’s better than the $100+ the other retailers not on Amazon sell these for. When using it after a little while, I feel my mouth and gums tingle in a good way when paring with Hydroxyapatite. Studies have shown benefits for the entire mouth using these lights, as a perk it also whitens your teeth. They have a warranty with this so I’m not worried in case it doesn’t last so long.

I purchased one of these back in July 2023. It worked great for 2 years, the battery started to get to the point wherein I couldn't get a full session out of it so I decided to order another one.I received the new one in July 2025. As of yesterday, not quite two months later, it has stopped working completely. I don't know what happened. When I put it on the charger it starts to flash but more dim than before. But it will no longer turn on.I am extremely disappointed. And because it's been more than the 30 day return window it doesn't look like I'll be able to get a refund on this. 🥺

This is helping my teeth remain white. And I think it might be helping my gums stay tight and strong against my teeth. Had some bone loss during covid, but recent X-rays show bone growing back. (Unlikely, but true.) I suspect this unit is part of the reason. I’ve had this for over a year. Easy to use. Charge it up, rinse or brush it before each use. Done. I use it 4-5 times a week. The unit needs more charging than when I first bought it, so it clearly has only so many uses built in before it stops working, but that’s fine. Will def replace when it dies on me. It’s fantastic for my oral health.
