Preston Dentist tips on Teeth Whitening At True Dental Care Preston, patients consistently ask us about whitening their teeth.

And there is no answer to the best way to do it.

The quickest and most effective treatment is usually an in-office professional whitening procedure, but it is not always the best option.

Depending on how dramatic you want the change to be, you may not require in-office whitening, and other techniques offer various advantages over it.

The best answer is to come to True Dental Care Preston and speak with us about your particular case and the type of whitening we recommend for it.

Optimal results are only going to be the result of professional treatment, and together, we can choose the best option for you.

At the same time, you should concentrate on keeping your teeth as white as they can be.

While only professional treatment can turn back the whitening tide, proper care and effort can keep your teeth as white as possible.

Why whiten your teeth?

White, attractive teeth that also look natural can help improve your appearance, self-esteem, and how the world perceives you around you.

Yellowing teeth are signs of aging, so a whiter smile can make you appear younger.

But whatever reason you desire professional teeth cleaning, whitening and veneers are fantastic, affordable, and relatively quick ways to achieve whiter teeth.

What causes stains and how to prevent them

There are two main categories of staining:

  • Extrinsic (external) staining is usually caused by habits – inadequate oral care, smoking, choice of food and drink.
  • Intrinsic (internal) staining usually caused by trauma, medication, or overexposure to fluoride while young.

Here is a quick list of what you can do about these stain/discolouration sources.

Food and drink cause extrinsic stains (outer surface of the tooth). To avoid these stains:

  • Rinse your mouth with water after eating or drinking.
  • Chew sugar-free gumto increase saliva flow and wash staining agents away.
  • Use whitening toothpaste while being careful about their abrasive quality.
  • Brush twice a day and floss once.
  • Get regular clean and checkups, scales and cleans if needed, to remove plaque, tartar, and surface stains.


Enamel thins, and roots become exposed as we age, which make your teeth look yellower. This can’t be prevented, but can be managed:

  • Brush with a soft or extra-soft toothbrush and don’t “scrub” the tooth surface.


Trauma can be partially avoided with the use of mouthguards when playing sports and splints to protect against grinding.

Whitening solutions

What about OTC/DIY whitening?

This is a relatively ineffective and dangerous choice. OTC and DIY kits contain high levels of chemicals, fewer precautions, and don’t have an expert (dentist) supervising.

They can cause enamel wear, revealing yellow dentin beneath. They can also harm health, burn gums, and damage the oesophagus or stomach.

In-chair whitening

In-chair whitening, conventional and Zoom, is slightly more expensive when compared to at- home whitening, but it is safer as a dental professional performs it.

In-office means a specially trained dental professional is the one applying the bleaching gel using safety measures including protective goggles, gels, and a lip retractor to minimise exposure between the bleaching gel and your gums and soft tissues.

With in-chair whitening, you come into our office, sit down to a professional treatment with whitening gel and special light, and then 1-2 hours later you leave our office with a smile that is up to 8 shades brighter!

At-home whitening

At home whitening gives all the control to the patient. You receive custom-designed trays to hold the whitening gel, and you apply them once daily, as instructed.

This allows more control of the whitening process, how long it takes, how white your teeth become, and who and what is in your mouth.

At-home whitening also serves as its own maintenance programs as you can touch up your whiteness at home.

Porcelain veneers

Veneers are great in cases of intrinsic stains, stains that can’t be removed, or for teeth with cosmetic problems in addition to the need for bleaching.

These wafer-thin shells are placed over the faces of your teeth and give you a stunning, white, regular smile.
