Over the last year, we’ve spent more face-to-face time with ourselves than any of us ever wanted. In the tiny box of a Zoom call, it can be easy to nit pick even the tiniest of details about ourselves - some rational, some less so.

If it’s the tint of your teeth that is causing you stress then you’re in luck, there are at-home whitening treatments that rival that of a professional and will help give you a confidence boost. With non-essential appointments cancelled, our collective gnashers could use some care and attention, so these are products that won’t cause more harm than good.

It’s easier than ever to take a proactive approach to your teeth care and encourage you to smile proud and wide. There are so many different types of products on the market including strips, trays and pens with a range of durability and to suit those with all levels of sensitivities. But before we get onto that, we’ve consulted two experts - leading celebrity dentist and founder of teeth whitening brand, Millionaire Smile, Dr Robbie Hughes and Dr Jeffrey Sulitzer, SmileDirectClub’s Chief Dental Officer - to find out everything you need to know about teeth whitening.

What causes discoloration of teeth?

Dr Jeffrey Sulitzer explains that it’s the food and drink that we consume as “the most common causes for teeth discoloration. In particular, coffee, tea and wine.”

Dr Robbie Hughes breaks it down further revealing that there are two types of staining; extrinsic and intrinsic where “extrinsic stains originate on the surface of the teeth, intrinsic dental stains come from within.

“Extrinsic stains can be yellow or brown in colour, but they can also be grey or white. These stains can be caused by drinking dark beverages like red wine, cola, coffee and tea or eating teeth-staining food like berries and highly pigmented sauces or curries. The number one cause of staining is smoking or chewing tobacco. This type of staining usually can be removed with a good oral hygiene routine and a good whitening toothpaste

“Intrinsic stains usually require in-practice solutions or prescribed peroxide whitening. These may form from fluorosis (this usually occurs when a young child is exposed to too much fluoride), the use of the antibiotic tetracycline, and pulpitis, the inflammation of the dental pulp. A build-up of plaque can also attract staining, therefore to help prevent all types of staining, we always recommend having regular appointments at least twice a year with your dentist or hygienist.”

Are home treatments effective?

Dr Hughes: “Each treatment works in different ways, the best method in terms of results is always an at home professional kit prescribed by your dentist, as the mouth trays are moulded to your teeth.Whereas when using pens, and strips, the saliva may make its way underneath the formulation and neutralise the whitening agent. We would also recommend speaking to your dentist first who will be able to recommend the best application or solution for you.”

How does professional teeth whitening work?

Dr Hughes: “In simple terms, there are two types of peroxide we use to whiten the teeth; carbamide peroxide and hydrogen peroxide. Peroxide works by oxygenating the tooth, which will break away the staining. This molecule changes how the light reflects off the tooth, making the tooth whiter.”

Are their downsides to teeth whitening?

Dr Jeffrey Sulitzer: “I wouldn’t say there were any downsides to teeth whitening, however it is important that you are a good candidate before going ahead. If you have fillings, bonding, or veneers on your front teeth, we would advise against whitening your teeth. This is because using teeth whitening with bonding or fillings may discolour your teeth further!

Dr Hughes: “The downside to whitening professionally is that sensitivity may occur. This is a very common symptom with whitening, however it is temporary and it is manageable. If you do experience pain or sensitivity, do contact your dentist who will be able to provide advice or treatment. If you are someone who does suffer extreme sensitivity with peroxide whitening treatments, a PAP whitening kit may be a better alternative as they contain 0 per cent peroxide meaning no pain or sensitivity.

“At-home or over-the-counter non-peroxide whitening treatments can be extremely effective when used properly, yet peroxide (prescribed) treatments are stronger which usually leads to strong results over a shorter period of time.”

What ingredients should you be looking out for in teeth whitening treatments?

Dr Jeffrey Sulitzer: “I recommend using at-home whitening products that contain hydrogen peroxide, as that’s the whitening agent that gives the best results. It penetrates the enamel to reach the discoloured molecules inside your tooth. Once hydrogen peroxide is applied to the tooth surface, it passes easily and quickly through tooth enamel, resulting in much whiter teeth.”

Dr Hughes: “We always recommend using a fluoride toothpaste as it helps prevent tooth decay by slowing the breakdown of enamel and increasing the rate of the remineralization process. Hydroxyapatite is a great ingredient also as it helps whiten the teeth, reduces tooth sensitivity, offers pain relief and helps fight both infections and cavities, whilst also remineralizing and repairing teeth.”

Total Whitening System

This teeth whitening set from Swiss Clinic works without the need for LED lights but this does mean that you need to use the product for longer. To customise the treatment to your teeth, you first set the mouthguard by placing it in hot water and then in your mouth so it moulds to the exact shape of your teeth. Next you apply the gel from the syringe and you keep it in for 45 minutes - and then an additional 15 or 20 after that for follow ups. It is delicate enough that you can use it daily until you achieve your sought-after results. This pack will see you through 18 treatments and has a long-lasting result. This set comes with the Teeth Whitening Pen too to give real bang for your buck.

Billion Dollar Teeth Whitening Strips x 28

Contrary to what the name suggests, a Billion Dollar Smile need not cost you an arm and a leg. This brand has got you covered with a Hollywood-worthy set of pearly whites that is actually a pleasant experience. This is mostly down to the fact that the strips have a subtle mint flavouring and only need to be worn for 15-30 minutes to still work effectively. They don’t include peroxide in the formula but still give immediate results, leaving your teeth significantly whiter especially when used daily for two weeks.

Wisdom Intense White Instant Whitening Pen

A teeth whitening pen gives you greater control over your treatment where you can target individual gnashers if needed. It has more of a paint brush applicator than a pen where you lather the gel, covering the teeth as needed. The most challenging part is trying not to close your mouth in the one minute directly after applying but when used persistently, Wisdom’s pen makes for an easy way to put confidence back into your smile.

It uses a blend of antioxidants like lavender oil, strawberry extract and honeysuckle flower extract to prevent causing further sensitivities and should be brushed directly onto teeth. The formula has a vanilla-mint taste, which is very welcomed particularly as the brand suggests for eating or drinking for 30 minutes after applying.
