The smile is one of the most important elements in our appearance and in the way we interact with others. However, over time, factors such as coffee, tea, wine, tobacco, and certain foods can stain teeth and dull our smile. Fortunately, teeth whitening is an increasingly accessible and effective cosmetic procedure that can restore a bright white tone to your teeth.
If you are considering teeth whitening, it is essential to know some key aspects before taking the step. At Clínicas La Guardia, we offer cosmetic dentistry and professional dental cleaning services designed to help you achieve lasting and safe results. Here, we share everything you need to know about teeth whitening and the care you should follow before and after the treatment.
What is Teeth Whitening?

Teeth whitening is a cosmetic procedure that involves applying a whitening gel to the tooth surface to remove stains and improve its color. There are different whitening methods, but at Clínicas La Guardia, we use high-quality products and advanced techniques that ensure visible results without compromising the health of your enamel.

Types of Teeth Whitening
At Clínicas La Guardia, we offer different whitening options tailored to the needs and expectations of each patient. Here are the most common types:
1. In-Office Whitening
In-office whitening is the fastest and most effective option. At Clínicas La Guardia, we use safe, high-quality whitening products containing hydrogen peroxide or carbamide peroxide. This type of whitening can brighten teeth several shades in a single session.
2. Supervised At-Home Whitening
We also offer at-home whitening kits designed so you can whiten your teeth from the comfort of your home under the supervision of our dentists. This type of whitening includes custom-made trays and a whitening gel that we will instruct you on how to apply safely.
Consult with our specialists to determine the whitening option that best suits you. At Clínicas La Guardia, we are here to advise you.
Pre-Teeth Whitening Care
Before undergoing teeth whitening, it is important to prepare your teeth to achieve the best results. Here are some pre-treatment care tips to consider:
1. Get a Professional Dental Cleaning
Professional dental cleaning is the first step before whitening. By removing plaque and tartar, cleaning allows the whitening gel to act evenly on the tooth surface. At Clínicas La Guardia, our specialists will perform a deep cleaning to maximize the whitening effects.
2. Check for Cavities and Healthy Gums
It is essential to ensure there are no cavities or gum problems before whitening. At Clínicas La Guardia, our dentists will assess your oral health and treat any issues that could interfere with the whitening treatment.
3. Avoid Staining Foods Before the Treatment
A few days before your whitening, try to avoid foods and beverages that may stain your teeth, such as coffee, tea, red wine, or dark sauces. This will help make the treatment even more effective and ensure longer-lasting results.

Post-Teeth Whitening Care
After whitening, it is important to follow certain recommendations to maintain the results for longer. Here are post-treatment care tips:
1. Avoid Staining Foods and Drinks
For at least 48 hours after whitening, avoid consuming foods and drinks that may stain your teeth. This includes coffee, tea, red wine, dark sodas, fruits like berries, and intense-colored sauces.
2. Brush Your Teeth with Toothpaste for Sensitive Teeth
It is common to feel some sensitivity after whitening. Use a special toothpaste for sensitive teeth for a few days to reduce discomfort. At Clínicas La Guardia, we can recommend the best toothpaste for you.
3. Maintain Strict Oral Hygiene
Oral hygiene is key to maintaining the white color of your teeth. Brush your teeth after every meal and use dental floss daily to prevent plaque buildup. This will help prolong the whitening results.
4. Consider Periodic Whitening Touch-Ups
Teeth whitening is not a permanent change; enamel tends to accumulate pigments over time. However, at Clínicas La Guardia, we offer the possibility of periodic touch-ups to keep your smile always bright.
Don’t forget to follow our team’s recommendations at Clínicas La Guardia after your whitening to ensure long-lasting results. Schedule a follow-up consultation to keep your smile impeccable.
