Q – Can you drink coffee while doing Enlighten?
A – Yes, you can eat and drink anything you like during and after the treatment. The Enlighten whitening process means no change in your diet. 

Q – Can I drink coffee with a straw after whitening?
A – Using a straw will help prevent any straining from the coffee on your teeth.

Q – How do coffee drinkers keep their teeth white?
A- Coffee drinkers are bound to have staining from consuming coffee in general. It is a harsh substance for your teeth, so to keep your teeth white while drinking coffee, Enlighten is the product for this. After your whitening treatment, you will be able to consume coffee, which will not affect or damage the whitening. 

Q – What hot drinks can I have after teeth whitening?
A – With some methods, tea and coffee are discouraged. However, with Enlighten there are no dietary restrictions.

Q – Can I drink water with Enlighten trays in?
A – Ideally not. However, if you need to, make sure you consume the water through a straw.

Q – How long after teeth whitening can I drink water?
A – You can drink water straight after.

Q – Is it okay to skip a day of Enlighten teeth whitening?
A – For best results, it is best to use the trays for 14 consecutive nights. For whatever reason, you may need to skip a day, just make sure to continue your treatment like normal after your missed day.

Q – How do I close the pores on my teeth after whitening? 
A – Great news! There is nothing you need to do about this, nature does all the work.

Q – Why do my teeth look yellow after whitening? 
A – If you have undergone the whitening treatment and seen little to no results, fret not – there are usually things that can be done to fix this. Insufficient whitening is the main culprit for such situations and the fix usually implies more whitening, but you HAVE TO contact your dentist and book a consultation to discuss your options and next steps.

Q – How long after teeth whitening can I brush my teeth?
A – Immediately.

Q – Can you use Enlighten during the day?
A – Yes, you can use it awake for a minimum of 3/4 hours. This will generally be advised if you grind your teeth at night.

Q – What is the best teeth whitening method?
A – A professional teeth whitening system prescribed by your dentist is the only way to whiten your teeth with lasting results. Use a system like Enlighten that guaranteed results. 

Q – How do celebrities get their teeth so white? 
A – Often very white teeth are achieved with veneers rather than whitening, but often these procedures can lead to bigger problems like staining or drilling of the teeth.

Q – Can 70-year-old teeth be whitened?
A – There is no upper age limit to whitening – however, with older patients it sometimes takes a bit longer. 

Q – Can yellow teeth become white?
A – Yellow teeth can be brightened with whitening or the colour can be completely changed by covering the teeth with veneers.

Q – How do dentists clean yellow teeth?
A – Hygienists can clean surface stains off a tooth by polishing them. The colour of the enamel can only be changed by bleaching/whitening

Q – Why are my teeth yellow when I brush them every day?
A – Teeth darken naturally with age, brushing too hard or staining foods – professional teeth whitening can reverse most of these effects. 

Q – Why won’t my teeth whiten? 
A – Seeing no results is rare, and it could be due to various reasons such as BRUXISM, superficial bleaching, or compliance. In such a situation, we advise getting in touch with your dentist and discussing a new treatment plan for you.


Q – Why Enlighten whitening didn’t work?
A – We tackle many difficult cases here at Enlighten successfully, however in rare cases this may be the problem, always contact your dentist who has your clinical records and carried out your treatment. 


Q – I have almost finished my treatment and I am still not at shade B1.
A – Continue the treatment until the end, and if you still suspect you are still not at B1 shade after the third week of your treatment then please contact your dentist. Get your dentist to get in touch with the Enlighten team, send some pictures, and explain the situation and we can tell you the best way to proceed. 



Q – Is it normal for gums to be red/irritated/sore?
A – It is not normal, but the good news is that gums are brilliant at healing themselves. Usually, irritated gum from overloading the tray with gel appears whiteish rather than red, and in that situation, take daybreak and next time apply less gel in the trays. If you suspect an allergy, stop using the gel straight away and contact your dentist. 



Q – My trays have small air pockets in and are worried if they are tight enough?
A – Firstly kudos to you for noticing such detail. The good news is that we made this on purpose. The air pockets and super-sealed margins ensure that the gel stays in contact with the tooth at all times, they are there for providing a better result.

Q – How much gel do I put in my trays?
A- You only need a lentil size or a small pea size amount of gel in each tooth.



Q – I have trays from previously whitening my teeth, can I purchase Enlighten and use them?
A – You can, but for the best results (for the B1 guarantee) you would have to use Enlighten trays. They are crucial in providing that ultimate result for multiple reasons: they are custom fit, provide better retention, super sealed margins, and the list goes on.

Q – Does the whitening treatment include any LED/UV-type lights?
A – No UV/LED lights will be used. Enlighten has invented a system where LED / UV lights are not needed. We provide custom-made trays that give maximum coverage and fit for your teeth.

Q – Is there an in-office appointment with my dentist?
A – No! The whole 3-week whitening treatment will be carried out in the comfort of your own home. However, If you do have any issues throughout your whitening treatment, then please contact your dentist.

Q – Does the teeth whitening gel need to be refrigerated?
A – Yes the Enlighten gel needs to be refrigerated. We have designed the gels to be PH stable so we can provide maximum results. 

Q – I have to stay away for a few nights between my treatment, how do I carry the gels?
A – To avoid complicated situations it is always best to time the whitening process when you are not traveling. However, if an unpredicted situation occurs then put your gels in a bag with an icepack and this should hold for travel. When you reach your destination, refrigerate the gels.

Q – Due to certain circumstances my gels have been out of the fridge for a long period of time and I feel uncomfortable using them. What shall I do? 
A – If this happens, please get in contact with your dentist to see if there is anything you will be able to do regarding replacement gels. Please don’t hesitate to contact us if you need further guidance

Q – How long does it take for tetracycline-stained teeth to lighten to B1?
A – Tetracycline staining can take anywhere between 2 weeks to 3 months to whiten.

Q – I suffer from sinus problems and it is difficult sleeping with the trays in, what is the daytime routine? 
A – It must be worn for 2-3 hours daily to achieve the maximum results.

Q – Some of my teeth are transparent?
A – Some areas can look more translucent as they dehydrate, this will return to normal within 2/3 weeks of the end of treatment.

Q – How many hours is it safe to keep your trays in?
A – We recommend keeping them in for as long as you’re asleep (as close to 8 hours as possible). If for whatever reason you have them in for longer than that, the gel won’t cause any damage to your teeth, it just stops working.

  1. Hi, if the effects of my initial whitening was not optimal or have faded, can I repeat the entire Enlighten treatment (eg redo consecutive 2 weeks of whitening with whitening gel, rather than once every month top up as recommended)?

    • Hi Melanie, in theory you can, especially if the first course was a long time ago but it is not always necessary. Sometimes top-up is enough and a lot more cost-effective. Always check with your dentist and ask for their advice. If the results weren’t long-lasting, there will be a reason for that and your dentist should be able to tell you what that reason would be in order to avoid that next time. Hope this helps.

  2. I have just done two nights with the trays and gel. I can taste the gel in my mouth while they are in (I wake up during the night). Does this mean they may be leaking? They feel well sealed but it feels like I may be swallowing some of the gel.

    • Rosanne, thank you for getting in touch. The gel is minty so the fact that you can taste it a little isn’t a problem as long as you’re not swallowing big quantities of gel and it doesn’t necessarily mean that the tray is leaking. The gel breaks down to water oxygen and urea, your body can deal well with all of those if I ingested in small amounts. There should be only a little excess of gel when you put the tray in which you wipe away with a tissue – if no more is coming out, then that should ok. But always check with your dentist if you’re worried, they can double check that the trays are a tight fit.

  3. I am on day 6 of week 2 of englighten. The sensitivity has been really intense since the beginning of my treatment but I have persevered and taken pain relief to help ease the pain where possible. I have ran out of desensitising swabs and todays pain is almost unbearable. Will there be a huge difference if I finish week 2 a day early or maybe switch to using the week 2 gel for 1 hour a day until it runs out then then moving onto week 3?

    • Hi Catherine, finishing week 2 one day shouldn’t have a huge effect on your results. You can keep that night’s worth of gel for top-ups 😊

  4. Hi there, do you provide lifetime warranty of trays? Eg if my tray wears out, or if my teeth have shifted overtime and they no longer fit. Thanks!

    • Hello Rebecca, thank you for getting in touch. No, we can not offer lifetime warranty on the trays. They are very well manufactured and they are durable however once the trays are in your care at home, you are responsible for keeping them in good shape and not distorting them. Avoid cleaning them with hot water and avoid keeping next to a source of heat as that leads to distortion. Always store them in the case provided to avoid losing them. Hope this helped!

      • Thanks for letting me know. What are my options if my trays no longer fit? They are still in good conditions but my teeth has shifted so the mould is no longer tight when I use them for top ups. What are my options?

        • Hello again. You’d have to get new trays made if that’s the case – this can be done through your dentist.

    • Hello Ingrida, we are the manufacturer of the product though and professional teeth whitening can only be done and purchased through a dentist so we cannot provide a price. It tends to range between £400 – £600. If you want to find an Enlighten provider near you, please click this link and pop your postcode in 👉🏼 http://find.enlightensmiles.com.
