Good preparation for whitening starts with an assessment of your teeth and gums. Your dentist can check what is causing discolouration, discuss the change you want and identify anything that needs treatment first.
Preparation reduces avoidable problems, but it cannot guarantee an exact shade or a treatment free of sensitivity. Knowing what whitening can and cannot change helps you make a more informed decision.
Check dental problems before starting
Tell your dentist about pain, sensitivity, bleeding gums, damaged teeth and any previous reaction to whitening. Active decay or gum disease needs attention before cosmetic treatment. Significant sensitivity also needs assessment rather than simply trying a weaker gel yourself.
A filling is not unsuitable just because it is old. The dentist will check whether it is sound or needs repair. Fillings, crowns and veneers do not whiten, so visible restorations can look different from the surrounding teeth after treatment. Discuss this before starting, including whether later replacement for colour matching might be appropriate. Do not replace a sound filling automatically just because you are considering whitening.
Whitening is not recommended during pregnancy or breastfeeding. Routine cosmetic whitening is not offered to under-18s.
Cleaning and daily care
Your dentist or hygienist may recommend professional cleaning to remove tartar and surface stains before whitening. The need and timing depend on your mouth; not everyone needs an identical set of cleaning procedures.
Continue gentle brushing with fluoride toothpaste and daily cleaning between the teeth. Do not scrub with powders, combine whitening products or start a stronger gel to speed things up. If you already have sensitivity, ask whether a desensitising product would be appropriate and how to use it.
Follow the preparation instructions for your particular system. You do not need to invent a restrictive diet or stop every coloured food several days beforehand. Ask the dental team if any product or instruction is unclear.
Choose a method and a realistic goal
Your starting shade and the cause of discolouration affect the result. A single dark tooth, especially after injury or root canal treatment, needs individual assessment and may require a different approach from whitening several healthy teeth.
With a dentist-provided home kit, custom trays hold the prescribed gel against your teeth. The dental team explains the amount to use, wearing time and review schedule. In-surgery whitening is another option, but a shorter appointment does not automatically make a result better or longer-lasting.
Our practice also offers Enlighten. Its manufacturer states that it guarantees Vita shade B1 and does not require a white diet. Your dentist should explain the proposed course and the guarantee as they apply to you. Do not assume that everyone needs exactly the same number or length of appointments.
Ask how the chosen method will fit around any planned veneers, crowns or fillings. Agree the sequence before starting so that colour matching and any additional costs can be considered together.
Fees and what to ask
Our home whitening tray kit costs £300. This is the fee for that listed service, rather than a quote covering all preparation or every whitening method. Check the current whitening fees and ask what your individual estimate includes, including reviews and any later top-ups.
Finance may be available subject to status, affordability and terms. Medical-Dent acts as a credit broker, not a lender. See our current finance information rather than relying on an old minimum-spend figure or assuming that every repayment period is interest-free.
After treatment
Keep following the instructions for your whitening system. Sensitivity or gum irritation can occur; contact the dental team for advice rather than increasing treatment or continuing through significant pain. Persistent symptoms need assessment.
A white diet is not a universal requirement, and Enlighten specifically says it is unnecessary for its system. Continue daily cleaning and discuss how to maintain the result, including any future supervised top-ups.
