Home teeth whitening kits with LED lights and gels are sold everywhere online. Some are cheap, some are expensive. Do any of them actually work — and are they safe? Here is what you need to know.

Most home whitening kits use the same basic science as professional treatment. A hydrogen peroxide gel breaks down stains on your teeth. The LED light is claimed to accelerate the process. But the concentration of peroxide in home kits is much lower than what your dentist uses.

The evidence is mixed. Some studies show a small improvement in tooth colour from LED kits. Others find that the light adds little to no benefit. The gel is doing most of the work — and the gel in home kits is simply weaker than what you get from a dentist.

You might see a slight improvement after several weeks of consistent use. But dramatic results are unlikely with most home kits.

This is where things get tricky. Some kits sold online have not been tested for safety. They may contain unregulated levels of peroxide. Others have poor-fitting trays that can leak gel onto your gums.

Gum burns, uneven whitening, and tooth sensitivity are common complaints. In rare cases, users have reported lasting damage to tooth enamel.

If you still want to try a home kit, look for one with the CE mark or FDA approval. Check the peroxide concentration — it should be below 0.1% for over-the-counter products in the UK. Avoid kits that make unrealistic claims or have no ingredient list.

Better yet, talk to your dentist before buying anything. They can tell you whether a particular product is likely to be safe and effective for your teeth.

Professional whitening is faster, safer, and more effective. Your dentist uses higher-quality materials and custom-fitted trays. You also get professional guidance throughout the process. If you are serious about whitening your teeth, professional treatment is the smarter choice.
