“It thought it worked great.”➕

“Clear Club whitening gel has been a game changer for achieving a noticeably brighter smile without sensitivity.”➕

“Most of the kits contain peroxides which essentially bleach your tooth enamel and remove superficial stains in the process.”➕

Boosts confidence with a nice smile

“Right! It help me boost my confidence and give me nice smile.”➕

Convenient LED light feature

“Do those teeth whitening kits (those you buy in drug stores that come with a light) actually work?”➕

Less irritation for sensitive teeth

“I’ve been using this for years and it is amazing! I have sensitive teeth and it is less irritating and whited better than the stuff i’ve paid an arm and a leg for at the dentist.”➕

Where it needs some work!

Areas to watch—feedback on possible improvements.

Ineffective whitening results

“How effective have you found the whitening? I have just received my kit! Doing impressions this weekend and will be returning and opting for the regular 22hrs a day treatment if suitable.”➕

“Personally not THAT effective, I took before and after pics and couldn’t really tell them apart... I did everything to the letter.”➕

“I haven’t found it to be effective at all. So...embarked on Colgate’s Optic White toothpaste AND mouthwash.”➕

Preference for other whitening methods

“I find Crest Whitestrips to be far better than the whitening solution SDC sends with the kit.”➕

“I didn’t notice a huge difference with this whitening pen system, so I even bought the special light from their website... still not a big difference.”➕

“I think it's a bit whiter but I should probably use it again and take before after photos.”➕

Gel/LED treatment may harm enamel

“I too heard and have read the gel+UV light harms your enamel and weakens the teeth.”➕

“Both of the gel/UV light treatment and whitening strips like crest are painful for me because I have very little enamel.”➕

“I completely agree with you, because if someone isn't careful they can very easily whiten away a good portion of their already weakened enamel and there really isn't a fix for that short of some hefty, pricey dental work.”➕

“I got one and within about 15 seconds of applying the gel stuff my teeth felt like they where burning so I quickly had to wash it off and haven't tried it since.”➕

Whitening strips were ineffective for some users

“Tried Crest whitening stripes didn’t work at all for me. And it does hurt a bit when you put them on, a strange burning like sensation.”➕

Core Power Plays

The specs and strengths that make it shine.

Discussion about various whitening methods and products

“They do work to some extent, but I feel like we tend to kinda expect results like we see on social media.”➕

“I also like the opalesence go prefilled whitening trays.”➕

“It worked great for me and it's one of those rare brands that don't use peroxide!!”➕

General discussion about teeth whitening methods

“Do they actually clear your teeth or is it more of a cosmetic coating?”➕

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’

General tips on whitening

“Thanks! I’ll look into the treatment ASAP”➕

“Sensodyne - spit and don’t rinse. If that’s not cutting it, ask your office about a desensitize treatment - lots of offices don’t charge, some do. It’s like a professional level of numbing agent for the teeth. Lasts about 3 months. And ask them to light cure it”➕

“Good question! I've always read it was 48 hours after in office (those formulas tend to be stronger than otc). In which case for otc, one would have to abstain for as long as they could before the next treatment, when the next treatment is like 12-18 hours. Let me take a look and see what I can find.”➕

“To be honest, they are all pretty much the same. I’m not really familiar enough with them to recommend one brand over the other. I can tell you that before you consider a home whitening kit, make sure all your teeth are in good shape. Any cavities, weak spots, or even degrading repair work can lead to increased sensitivity. Anyone who has braces or permanent retainers should speak to a dentist. Honestly, the best thing to do is to see your dentist for a checkup and teeth cleaning before using anything so that any potential problems can be discussed. There are many cleaning procedures that can be done in the office, although they are more expensive than the home kits and as they are cosmetic, unlikely to be covered by insurance. Also, don’t expect miracle results. Years of coffee stains don’t come off in two weeks. Some types of stains remove better than others. If you really want white teeth, buy a whitening toothpaste (any name brand will do) to supplement the whitening strips. You’ll be amazed what can happen in three months.”➕

Comparison of various whitening methods

“Hydrogen peroxide from the pharmacy is like 3% and professional gels with a little higher concentration are supposed to stay on teeth for several hours for at least few days to work.”➕

“A hygienist family friend once told me long term use of the white strips are awful for your teeth is that true?”➕

“Yes, it can be! A certain amount of exposure can soften the dentin of your teeth, and then it's easier to damage that enamel after the process.”➕

Discussion about effective teeth whitening options for sensitive teeth

“So I thought I'd share it with you guys, in case anyone's looking for something to help with whitening.”➕

“Thank you soooo much for this, I am a sensitive teeth girly and love my coffee. I will def be ordering the Auraglow!.”➕

Concerns about effectiveness of social media recommendations

“TikTok is full of them but it’s so hard to know which ones are legit and which ones are just influencers hyping them to earn money.”➕

Discussion about alternative whitening solutions

“Yeah the solution is to go with the lowest strength product in combination with a sensitivity whitening toothpaste, imo”➕

General tips on maintaining teeth whiteness

“Teeth whitening pens are ideal to correct the whiteness of your teeth.”➕

General tips on teeth whitening kits

“Good teeth whitening kits that actually work? Does anyone recommend any teeth whitening kits that actually work? I am looking to spend no more than $100.”➕

“The crest strips 3D work really well! Also, start with charcoal toothpaste it works instantly.”➕

“Honestly, hands down one of the best kit is PlusWhite 5 minute white. Its $8 from Walmart or $12 on Amazon. I will use it 3-4 times in one week and then wait a few months before repeating. Doesn't make my teeth sensitive.”➕

“I’ve use the Crest White Strips several times and they are good but I’ve recently upped my game and started using a White With Style kit. It’s a little bit more work to make the molds in the beginning but it’s cheaper than white strips and I’m loving the results.”➕

Discussion about the effectiveness of different whitening methods

“The gel stuff is what does 99% of the work.”➕

Cautionary Callouts

Know the pitfalls before they catch you off guard.

Discussion about peroxide's effectiveness

“The only thing that will whiten your teeth with any significance is a peroxide.”➕

“Your gums will recede and there’s a heightened chance of oral cancer.”➕

“So..can I just rinse w/hydrogen peroxide and save $$ on strips?”➕

Sensitivity concerns with whitening

“I wonder if receding gums come into it at all.”➕

“More expensive though”➕

“BIG MISTAKE! My teeth were painful for the next 4 days, just throbbing even if I ran my tongue over the tops of the teeth.”➕

“Decreased my sensitivity 100 fold”➕

Discussion about various teeth whitening kits

“I read a lot of post and articles. And I have come down with this list.”➕

“I ended up getting Auraglow because a lot of people mentioned it.”➕

“I’ve tried the Clear Club whitening kit, and it’s been great for my sensitive teeth.”➕

“Consulting with my dentist, products like Crest 3D Whitestrips, AuraGlow Teeth Whitening Kit, and Smile Direct Club's Teeth Whitening Kit.”➕

Concerns about teeth sensitivity with whitening kits

“Most dentists use peroxide based gels to whiten teeth, but by covering the gums and other sensitive areas, discomfort is reduced.”➕

Concerns about sensitivity with whitening products

“Most whitening solutions are going to cause sensitivity in teeth with reduced enamel.”➕

Concerns about the safety of whitening products

“Do they really work? Do they harm you enamel and weaken your teeth?”➕

“I’ve also heard those charcoal black tooth pastes grind off yours enamel.”➕

“If you already have weak teeth, the impurities removed could really cause some damage and/or pain.”➕
