How Long Does Laser Teeth Whitening Last?

One of the most common questions we hear at The Pearly Bright Glasgow is: “How long will my laser teeth whitening last?”

The honest answer is… it depends. Results vary from person to person, because lifestyle habits, diet, and aftercare all play a huge role.

What affects how long your laser whitening lasts?

• Diet & drinks
  Coffee, tea, red wine, fizzy drinks, curries and dark sauces are the biggest culprits when it comes to staining teeth.

• Smoking & vaping
  Nicotine and vapour can dull results much faster, meaning smokers may need more frequent top-ups.

• Oral hygiene
  Daily brushing, flossing and rinsing (with a gentle toothpaste like Naturawhite) help keep teeth looking brighter.

• Your natural enamel
  Everyone’s teeth are different. Some people naturally hold brightness longer, while others may need more regular refreshes.

On average, how long does it last?

Many clients choose to have a top-up session every 2-3 months to keep their smile at its best.

Tips for keeping your laser whitening results longer

• Drink staining beverages through a straw when possible.

• Brush with Naturawhite toothpaste or another gentle, enamel-friendly option.

• Rinse with water after coffee, wine, or strongly coloured food.

• Book regular top-up sessions to maintain your glow.
