Crest Whitestrips Professional Effects

A Deep Dive Into Crest Whitestrips:

Crest has been a trusted brand in dental products for many years, and is trusted by professionals in the field to deliver quality results to their customers. Crest Whitestrips are no exception; the product gives a professional whitening with minimal mess or effort.

The product consists of a chemical strip that can be applied directly to the teeth, without the need for extra adhesive or any external apparatus to hold it in place. After a relatively brief wait, the strips can be peeled away and discarded, revealing an immediately whiter smile – effects should be noticeable in a minimum of three days.

Crest Whitestrips are effective on years of built-up discoloration and staining – even those that have neglected their dental health can still see definitive results after only a few uses. The strips can be easily molded to fit the mouth, including around missing or damaged teeth.

Depending on the individual needs of the customer, there may not be need for a full package at once – some people may be happy with the effects of only a few strips, and opt to leave the rest for later instead of finishing the treatment. Crest Whitestrips are made with this eventuality in mind, made to be shelf-stable for well beyond twelve months.

Unlike tooth brushing or flossing, which are normally added at the beginning or end of the day, Crest Whitestrips can be used at any time of the day – simply apply them and wait the prescribed thirty minutes. That said, users should make certain their teeth are clean before use, as food or other debris will prevent the strips from working in contact with the user’s teeth.

Although they do give the appearance of cleaner teeth, It is important to remember that these strips are not a substitute for  proper dental care routines. Toothbrushing, flossing, and gum care with a dedicated gum care product like Dental Pro 7 all remain an important part of the day even when this product is in use.

Who’s It For?

This product is designed for anyone that might want a whiter smile without the need for costly procedures or the inconvenience of a professional appointment. The strips are easily applicable and  mold quickly to the shape of the user’s teeth, whatever the damage or dislocation.

This product is not for use on those missing teeth, either due to infancy or injury; the chemical whiteners are not intended for the gums and prolonged contact can be irritating or even harmful to the exposed areas. Users should also take care that they are not allergic to any of the chemical components; direct application in the mouth can aggravate even relatively mild allergies to a dangerous degree.

What We Like About Crest Whitestrips:

This product is a solution for what many people are really seeking in an intensive dental care regimen – a clean smile no matter what their age or dental health. Although there is an unquestionable element of proper tooth care involved, the desired end result is always whiter teeth, and Crest Whitestrips can cut straight to the end at fractions of the cost of the rest.

What We Don’t Like About Crest Whitestrips:

Despite their considerable cosmetic effects, the simple fact remains that this product is just that –  a cosmetic item that does not properly address existing or developing dental disorders. A satisfied user or this product could mistake it for proper tooth care and become convinced that they are taking proper care of their teeth – a process akin to saying a hole in a wall is fixed simply by painting over it.


  • Immediate effects
  • Easy to use
  • Short treatment period
  • Conforms to disfigured teeth
  • Considerable shelf life


  • Cannot reach between teeth
  • Can be mistaken for proper dental care

What’s Included:

As this product applies directly to the teeth, the package is understandably minimalistic. Every box contains forty individually wrapped strips, allowing for up to twenty treatments on the upper and lower lips with each purchase.

Not included is any means of gauging the user’s progress; many similar products will include a visual scale to help the user judge their progress, a notable omission from this one. Crest should also include a warning that these are not a substitute for proper tooth care, and perhaps even recommend methods to address that deficit.

Overview Of Features:

The main feature of Crest Whitestrips is the results they produce; many users report seeing a definitively whiter smile well before they have used the entire package. These effects have been reported on every condition from simple aging to the heavy staining caused by drinks like coffee or tea, and even on calcification and yellowing that results from serious neglect of one’s oral hygiene.

The product weight is understandably low, making it easy to carry around throughout the day and apply whenever a pristine appearance is important. A shelflife of more than a year means that once the desired whiteness is achieved, any extras can be stored and used for touch-up without fear of losing their potency.

The adhesive action is a combination of the strip’s composition and natural salivary moisture and adheres the strip to the tooth with no discomfort or damage to enamel. The resultant bond is strong enough that users can talk, swallow, and even drink with the strips still in place, making them far more convenient than trays or mouthguards intended for the same purpose.

It is worth mentioning that the strips do not dissolve during use; once the whitening gel has been completely absorbed into the teeth, the plastic backing will need to be removed and discarded. Users should be careful to avoid ingesting the strip by accident, and take care to discard it out of reach of children, as it can be a choking hazard.

Review Summary:

Crest Whitestrips are an easy and effective solution to nearly any problem of tooth discoloration, from aging to staining. They will form a helpful part of any user’s cosmetic routine, but should not be mistaken for proper dental hygiene.


How Long Does it Take for Crest 3D Whitestrips Professional Effects to Work?

Crest’s 3D Whitestrips work by penetrating the tooth enamel to eliminate stains. The strips contain a gel made of carbamide peroxide and hydrogen peroxide. When the strip is placed on your teeth, that gel is what works to get rid of stains. They can remove up to 14 years of stains.

Typically, you will start seeing results in 3-5 days, but you won’t see the full result until about 15-20 days. Make sure you apply the strips daily as instructed, as missing a day can affect results. 

Should I Use Whitening Strips in the Morning or at Night?

Whitening strips will work equally effectively whether you wear them in the morning or at night. However, there are some things to take into consideration. Eating or drinking anything that can stain your teeth (such as coffee or tea) may affect results. Although they will stain your teeth, either way, it’ll just be more noticeable after whitening. 

Another thing to consider is teeth sensitivity. Most whitening strips can cause discomfort for people with sensitive teeth or cavities. In this case, it may be best to do it at night before bed to avoid that. If you use them at night, brush your teeth before using them and not after.
