Tooth whitening is an aesthetic treatment that seeks to lighten the tone of teeth, eliminating stains caused by various factors. There are different types of teeth whitening and it is important to know their characteristics and aftercare. The results can last between one and three years and some temporary side effects may occur, but the treatment is safe and effective. Although there are home methods, it is advisable to go to professionals to obtain the best results and avoid damage to dental health.
The importance of teeth whitening
Teeth whitening is a cosmetic treatment that is increasingly in demand by those who wish to improve the appearance of their smile. It is not surprising considering that the smile is one of the most visible and attractive features on a person.
Having bright white teeth can have a significant impact on a person's confidence and self-esteem. Whiter teeth not only improve aesthetic appearance, but also convey a healthier and more cared-for image.
The passage of time, the consumption of certain foods and drinks, smoking and some medications can stain and darken teeth. These stains can be difficult to remove with daily oral hygiene, which makes tooth whitening an option to consider to restore the natural colour and brightness of teeth.
Teeth whitening can help to effectively remove stains and discolourations, restoring teeth to their lighter shade and whiteness. This not only improves the appearance of the smile, but can also rejuvenate the overall facial appearance.
Moreover, tooth whitening is a non-invasive procedure that offers fast and long-lasting results. Unlike other cosmetic treatments, such as dental veneers, tooth whitening does not require permanent modification of tooth structure.
Myths and truths about teeth whitening
There are many myths and misinformation surrounding tooth whitening. Here are a few of them:
Myth 1: Tooth whitening damages the tooth enamel.
It is common to hear that tooth whitening can damage tooth enamel. However, this is incorrect. Professional tooth whitening performed in a dental clinic does not damage tooth enamel if it is done correctly, following the dentist's instructions. It is important to rely on trained professionals to perform this procedure and avoid home remedies that could cause damage.
Myth 2: Teeth whitening is a substitute for teeth cleaning.
It is important to be clear that tooth whitening is not a substitute for dental cleaning. Both treatments have different purposes. Oral cleaning is responsible for removing bacterial plaque and tartar build-up, while teeth whitening focuses on lightening the shade of the teeth. It is advisable to perform both treatments in a complementary way to maintain a healthy mouth and an aesthetic smile.
Myth 3: Baking soda and lemon whiten teeth
There is a belief that baking soda and lemon can naturally whiten teeth. However, this is a myth. Both baking soda and lemon are abrasive and their frequent use can wear down tooth enamel, causing sensitivity and even permanent damage. It is important to avoid these home remedies and opt for safe and effective professional treatments instead.
Myth 4: Hydrogen peroxide is effective for whitening teeth.
Another common myth is that hydrogen peroxide can whiten teeth. However, its use is not recommended, as it can irritate gums and cause damage to oral tissues. Furthermore, it does not provide the desired results and its incorrect use can have negative consequences for oral health. It is better to opt for professional treatments endorsed by specialists.
It is important to dispel these myths and have accurate information about tooth whitening. Consulting a trained professional is essential to clear up any doubts and obtain a personalised and safe treatment.
Types of tooth whitening
There are several types of teeth whitening, each with its own characteristics and benefits. Below, we will explain the most common ones:
1. In-clinic tooth whitening
This type of whitening is performed in the dental clinic under professional supervision. A highly concentrated whitening gel is applied to the teeth, which is activated by a special light source. This procedure usually provides immediate results and can be more effective in cases of severe staining.
2. Outpatient tooth whitening
Outpatient tooth whitening is performed at home with the help of a kit provided by the dentist. It involves the use of customised whitening trays containing a moderately concentrated whitening gel. These trays are worn for several hours a day, usually for a period of weeks. Although results may take longer to be seen, this method is more comfortable and allows for greater control of the process.
3. Tooth whitening with strips
Whitening strips are thin, flexible strips impregnated with a whitening gel. They adhere easily to the surface of the teeth and are used for a set period of time on a daily basis. Although they are a cheaper and easier to use option, the results may be less pronounced compared to other methods.
4. Tooth whitening with LED lamp
This type of whitening uses a low-intensity LED lamp to activate the whitening gel applied to the teeth. The light emitted accelerates the whitening process, which can result in a reduction of the time needed to obtain visible results. However, it is important to follow the dentist's instructions to avoid tooth sensitivity.
5. Tooth whitening with over-the-counter products
There are a wide variety of whitening products available over the counter in supermarkets and pharmacies, such as whitening gels, toothpastes or rinses. While they may offer subtle results in some cases, it is important to note that their effectiveness may be limited and they are not professionally supervised.
Remember that each type of teeth whitening has its own advantages and considerations. If you are interested in having your teeth whitened, consult with your dentist to determine which option is best for you and make sure you follow all the recommended instructions and care during the process.
Side effects of tooth whitening
When teeth whitening is performed, some temporary side effects may occur. These effects are usually mild and go away on their own in a short time. It is important to be aware of them so that you are prepared and know what to expect after treatment.
- Dental sensitivityThe most common side effect is characterised by a sensation of sensitivity in the teeth. It can manifest itself as mild discomfort or a sharp pain when consuming cold, hot or sweet foods or drinks. However, this sensitivity is usually reversible and disappears within a few days or weeks.
- Gingival irritationSome people may experience redness, swelling or irritation of the gums after tooth whitening. This may be due to the whitening gel coming into contact with the gums during treatment. This irritation is usually temporary and disappears in a short time.
- White spotsIn some cases, white spots may appear on the teeth after whitening. These stains are caused by temporary dehydration of the tooth enamel and usually disappear within a few days.
- Irritation of the oral mucosaOccasionally, contact of the bleaching gel with the oral mucosa may cause irritation or mild burns. These effects are usually temporary and disappear quickly.
It is important to mention that these side effects are temporary and do not represent significant risks to dental health. However, if symptoms persist or worsen, it is recommended to consult a dentist for appropriate treatment and advice.
If you have any doubts or concerns about the side effects of teeth whitening, it is advisable to consult a trusted professional, who can provide the necessary care and advice to ensure a safe and successful treatment.
Care after tooth whitening
Once teeth whitening has been carried out, it is essential to follow a series of precautions to maintain the results and protect dental health. Here are some recommendations that you should bear in mind:
Avoid foods and drinks that can stain teeth.
After teeth whitening, it is important to avoid or reduce the consumption of foods and drinks that can cause staining of the teeth, such as coffee, tea, red wine, carbonated beverages and foods with strong colourings. These can compromise the duration of whitening results.
Maintaining good oral hygiene
It is essential to continue a proper oral hygiene routine, including brushing after every meal, flossing daily and using mouthwashes. This will help remove food debris and prevent stain build-up.
Avoid tobacco and alcohol consumption
Both smoking and excessive alcohol consumption can compromise the longevity of teeth whitening results and cause additional staining of the teeth. It is advisable to avoid or reduce their consumption to maintain a healthy, white smile.
Regular visits to the dentist
It is essential to continue with regular visits to the dentist for check-ups and dental cleanings. The professional will be able to assess the state of your teeth and offer you personalised recommendations to keep your whitening and dental health in optimum condition.
Use appropriate dental care products
To maintain the results of teeth whitening, it is advisable to use specific tooth care products, such as whitening toothpastes and mouthwashes or formulas that help maintain the colour of your teeth. Consult your dentist for recommendations on which products are right for you.
Duration of tooth whitening results
One of the things to consider when opting for teeth whitening is how long the results will last. While teeth whitening can produce a noticeable change in the colour of teeth, it is important to keep in mind that this is not a permanent treatment.
The duration of tooth whitening results varies from person to person and depends on a number of factors. Some of these factors include the individual's biology and habits, as well as the quality of the tooth enamel and post-treatment oral care.
In general, it is estimated that the results of teeth whitening can last between one and three years. However, it is important to note that the whitening effect may gradually diminish over time due to exposure to pigmented foods, drinks such as coffee or red wine, and other habits that can stain teeth.
It is important to mention that proper maintenance and aftercare after teeth whitening can extend the duration of the results. This involves maintaining good oral hygiene, regular brushing, flossing and regular visits to the dentist.
In addition, there are specific tooth care products, such as whitening toothpastes or mouthwashes, which can help to maintain the whitening results for longer.
It is essential to keep in mind that each person is unique and that the duration of results may vary. Some individuals may experience a more rapid loss of whitening effect, while others may maintain results for longer.
In any case, if you want to maintain the results of teeth whitening in the long term, it is advisable to reduce the consumption of foods or drinks that can stain teeth and to maintain a good oral care routine.
