How to Whiten Your Teeth Safely and Fast?

Whether you need a quick touch-up, you’re trying to establish a dental whitening routine or it’s self-care night, at-home dental teeth whitening kits are a quick way to get a pearly and confident smile.

Gone are the days when we had to go through the hassle of calling our dentist’s office to schedule an appointment (that would inevitably cost an arm and a leg!). DIY LED teeth whitening kits have made it really convenient and cost-effective for us to tackle tooth stains from the comfort of our home.

So, if you’re wondering how to whiten your teeth safely and fast, we’ll guide you through the process step by step. But first, let's take a moment to understand why our teeth get yellow in the first place.

 What Causes Yellow Teeth?

Why are your teeth turning that dreaded yellowish hue and what can you do to brighten it? Dental discolouration may be a result of:

  • What You Eat & Drink

Some food items and beverages such as berries or red wine are rich in tannins which are organic plant-derived biomolecules. As tannins build up on enamel (the outer protective layer of our teeth), they cause tooth stains. Excessively consuming these foods is linked with long-term discolouration. Avoiding beverages such as coffee, soda and wine can go a long way into preserving your enamel and keeping your teeth stain-free in the long run.

  • Smoking

One of the top causes of dental discolouration is smoking. Not only does smoking damage your teeth, but it also leaves stubborn stains on the teeth - but that doesn’t mean smokers cannot take steps to prevent this damage.

If you smoke, start by cutting down on cigarettes or better yet quitting them altogether. Establish an oral hygiene routine, brush, floss and gargle with a whitening mouthwash after every meal. One of the best ways to counter stubborn stains is to get a teeth whitening kit for sensitive teeth.

  • Medical Conditions or Medications

Some diseases or medicines may also cause yellow teeth. These include chemotherapy, medicines prescribed for asthma and high blood pressure.

  • Lack of Dental & Oral Hygiene

Having a dental and oral care regimen in place is essential if you want to keep your teeth healthy, white and bright - but it's equally important to also remember that our teeth naturally get yellow with age because our enamel gets sloughed away.  

  • Fluoride

Higher concentrations of fluoride may also result in yellowing teeth. This is especially common in young children.


Since your teeth can go yellow for various reasons, setting up an in-house consultation with an expert dentist can help you determine what’s making your teeth go yellow.

So if you’re wondering how to whiten your teeth safely and fast, here’s how to give yourself an at-home smile makeover using the best teeth whitening kit, here’s a step-by-step guide:

What You Need:

  • LED Teeth Whitening Kit:

You can pick between wireless LED teeth whitening kit  or a LED smartphone teeth whitening kit. Each LED teeth whitening kit has the following contents:

  • A mouth-tray studded with 24 LED lights
  • Two Dental Grade Teeth Whitening Gel Pens (20 Treatments)
  • A Comprehensive Instruction Manual
  • A Shade Guide
  • A USB Charger/ Adapter


  • Post-Whitening Care: Minerals Enamel Booster


Total Time:

 30 mins - 60 mins (consult instruction manual enclosed in the package to estimate the accurate time)


Step 1: Read the Instruction Manual

You must review the instruction manual that comes with your LED teeth whitening kit before starting with your at home whitening treatment. This manual contains more detailed guidelines about how to use this simple and convenient LED teeth whitening kit at home.

Step 2: Rinse Your Teeth and Dry It

Begin by rinsing your teeth with lukewarm water and then drying it.

Step 2: Apply the Carbamide Gel and Insert the Mouth tray

Take out one of your teeth whitening gel pens and gently cover your teeth with a layer of gel. Each pen contains 2 ml of carbamide gel (carbamide peroxide: 44%). This gel is formulated using GMO-free and kosher and vegan ingredients.

The whitening gel pens make it super easy to apply the gel onto your teeth. Just coat your teeth with it and follow the directions printed on your manual to properly place the LED teeth tray in your mouth.

Step 3: Relax or Catch Up on That Season You’ve Been Watching

This is the beauty of at-home dental whitening rituals: you get to pick a time and place of your liking. So, settle down in a comfy corner and wait (according to the time duration specified in guidelines). You can catch up on that recent series you started watching on Netflix, paint your nails or read a book, the choice is yours.

Generally, carbamide peroxide cleans superficial stains immediately but it takes a bit longer for the gel to deep cleanse your teeth and penetrate your dentin, the inner layer of your teeth where most of the whitening action begins.

You may have to wait 15-20 mins while carbamide peroxide opens your pores, it takes another 20 minutes for the natural bleaching agent to reach your dentin. In the next 20-30 minutes, you will begin noticing visible results. The LED lights speed up the process, deep cleanse your teeth and protect your gums throughout this process

*The times stated may vary (check the manual for specific timings)

Step 4: Rinse Again

Depending on how yellow your teeth presently are, you’d be done in 30-60 minutes. Once you’re done, take out your mouth guard, rinse your mouth with water - and smile away!

After Care: Apply Minerals Enamel Booster

If you have tooth sensitivity or you want your teeth to remain healthy, use a Mineral Enamel Booster pen  to remineralise your teeth. Teeth whitening procedures are safe but may result in the enamel getting stripped of its essential mineral. Using the mineral enamel booster after your LED teeth whitening treatment is the best way to replenish your enamel.
