A white, radiant smile is much more than aesthetics; it reflects health, confidence and well-being. At Biodent, your dental clinic and medical centre in Torrevieja and Ciudad Quesada (Alicante), we know that the wish for a brighter smile is a common one. That is why teeth whitening has become one of the most popular and effective cosmetic treatments. But what does it actually involve? In this article we unravel all the secrets of teeth whitening: what it is, the types available and how to keep those dazzling results.
What Is Teeth Whitening and How Does It Work?
Teeth whitening is a safe and effective cosmetic procedure designed to lighten the shade of your teeth, removing stains and discolouration that build up over time. These stains can be caused by coffee, tea, red wine, tobacco, certain strongly pigmented foods or simply natural ageing.
The process is based on applying whitening agents, mainly hydrogen peroxide or carbamide peroxide. These compounds penetrate the enamel and dentine of the teeth, where they release oxygen. As it breaks down, the oxygen splits the pigment molecules that cause the staining, making the teeth look lighter and brighter. It is essential to understand that this process does not damage the tooth structure; it simply acts on the stains.
Types of Teeth Whitening
There are several types of teeth whitening, each with its own characteristics and advantages. The most suitable one for you will depend on your needs, the degree of staining and the advice of our specialists at Biodent.
In-Clinic Teeth Whitening
- It is the fastest and most effective method.
- It is carried out at the dental practice under the direct supervision of a professional.
- Whitening gels with a higher peroxide concentration are used.
- It is often combined with an LED light or laser lamp to activate the product and speed up the results.
- It offers visible results in one or just a few sessions.
At-Home (Take-Home) Teeth Whitening
- The dentist takes impressions of your teeth to create custom-made trays.
- You are given a whitening gel with a lower concentration to apply in these trays.
- It is used at home for a set period (usually a few hours a day or overnight) over several weeks.
- It requires regular follow-up and supervision by your dentist.
Combined Teeth Whitening
Considered a method with particularly long-lasting results, it combines in-clinic whitening with the take-home system. The initial in-clinic session provides a significant boost, and the treatment at home helps consolidate and prolong the effects.
Internal Teeth Whitening
This type of whitening is applied to teeth that have had root canal treatment (endodontics) and have darkened over time. The whitening agent is placed directly inside the tooth and temporarily sealed.
Is Teeth Whitening for Everyone? Important Considerations
Although teeth whitening is a safe procedure, it is not suitable for everyone. A thorough prior assessment by your dentist at Biodent is essential to determine whether you are a good candidate. Some factors to consider include:
- Oral health: Before any whitening, there must be no cavities, active gum disease or infections. Any dental problem must be treated first.
- Tooth sensitivity: People with high sensitivity may experience a temporary increase in it.
- Restorations: Whitening does not change the colour of dental restorations (fillings, crowns, veneers). If you have these on front teeth, you may need to replace them after whitening so that they match the new shade of your natural teeth.
- Medical conditions: It is not recommended for pregnant or breastfeeding women, or for anyone under 18.
Tips to Maintain Your Whitening Results
Once you have achieved the smile you want, certain habits are crucial to prolong the effects of the whitening:
- Strict oral hygiene: Brush your teeth at least twice a day, floss and use mouthwash.
- Avoid staining food and drinks: Cut down on coffee, tea, red wine, cola drinks, berries, dark sauces and tobacco — especially in the first days after the treatment, when the teeth are most prone to staining.
- Regular check-ups and cleanings: Visit your dentist at Biodent for regular check-ups and professional cleanings, which help remove surface stains.
- Top-ups: Over time it is natural for the colour to darken slightly. Your dentist may recommend periodic top-ups (usually with the take-home system) to maintain the brightness.
