What is oral health?

Oral health is the absence of diseases, pain and, generally, any type of problem that affects the good condition and/or function of the oral cavity, teeth and gums.

What is dental biofilm?

Dental biofilm (dental plaque) is an accumulation of microorganisms surrounded by a film that originates from the saliva and remnants of food and attaches itself to the different parts of the oral cavity. Dental plaque is barely visible or not visible at all, unless it becomes pigmented (food, bacteria, tobacco, etc.) or mineralised (dental calculus or tartar). It is the main agent responsible for tooth decay and periodontal diseases.

How can I prevent oral diseases?

Eating habits and hygiene play a crucial role in the development and protection of teeth and gums. Oral diseases and conditions can be reduced by eliminating common risk factors such as: a lack of adequate oral hygiene, tobacco and eating nutritionally deficient food.

What are the most common oral diseases?

The most common oral problems and diseases:


Tooth decay is a multifactorial disease, characterised by the demineralisation of the tooth structure, starting with the enamel and progressing towards the dentin. Unless properly treated, it will continue to progress until it affects the pulp (nerve of the tooth), causing severe pain until the entire tooth is destroyed.

Decay can be prevented by using mouthwashes and toothpastes with fluoride. In certain cases, the application of fluorides by professionals is also advisable.

Periodontal disease

Periodontal disease affects the gums and the tissue that supports the teeth. If an inflammation or bleeding of the gums is detected during normal toothbrushing, it is most likely a case of gingivitis which, if untreated, may lead to periodontitis, a disease characterised by receding gums and detachment from the teeth, resulting in their loss.

To prevent this, it is necessary to maintain excellent oral hygiene, avoid the use of tobacco and to visit a dentist regularly so that they can examine the condition of your mouth. It is important to have a proper professional dental cleaning at least once a year.

Dry mouth syndrome

Dry mouth syndrome, also known as xerostomia, is a condition that affects 25% of the adult population. This conditions consists of a decrease in the amount of saliva produced, due to an impairment of the salivary glands, which may be caused by: the side effects of medication, psychological disorders, tobacco, certain medicines, radiotherapy or dehydration Xerostomia is an important health problem, as it causes numerous organic disorders and multiple oral lesions that affect your quality of life.

Eliminating the factors that reduce the amount of saliva that is produced (alcohol and tobacco), stimulating saliva production, keeping hydrated and frequently drinking water will help you to fight this disease. Using products specifically designed for this type of condition, such as the KIN Hidrat brand: artificial saliva, bioadhesive gels or toothpaste, helps to alleviate a dry mouth and improve your quality of life.

How does diet affect oral health?

Nutrition plays an important role, not only in having good overall health, but also in the development and protection of oral and dental health. Ignoring the symptoms of diseases and problems with oral function is harmful for your health.

The key to good nutrition is not avoiding certain types of food, but eating them in moderation. It is essential to have a balanced diet and avoid snacking between meals. A balanced diet consists of eating a wide variety of food, from each of the five main groups:

  • Bread and cereals
  • Vegetables
  • Fruit
  • Meat, poultry and fish
  • Milk and dairy products

If you snack between meals, it is important to eat food that does not contain too much free sugar, as this does the most damage to our teeth. Instead, opt for nutritional food like cheese, nuts, raw vegetables or fruit.

Do Laboratorios KIN's oral care products contain milk derivatives (lactose, cow's milk protein or derivatives)?

No. Laboratorios KIN’s oral care products, including those designed for use by infants and children, do not contain milk or any type of milk derivative.

Are Laboratorios KIN's oral care products suitable for use during pregnancy?

Yes. Generally, toothpastes and mouthwashes can be used without any problem during pregnancy, provided that they are used for their intended purpose and always following the directions for use that appear on their labelling.

In this respect, GingiKIN B5 toothpaste and mouthwash are highly recommended for gum maintenance and preventing oral problems during pregnancy. In any event, during pregnancy, you should always consult a doctor or dentist for better monitoring of treatment.

When can I undergo tooth whitening?

The loss of natural colour due to ageing, yellowing due to bad habits like tobacco, the darkening of teeth and staining due to conditions unrelated to oral hygiene or dietary habits are some of the reasons why it is advisable to undergo tooth whitening.

You should never undergo tooth whitening treatment, such as using whitening toothpaste, without first consulting a dentist, in particular in the case of children under the age of 12, women who are pregnant or people with tooth decay or other oral diseases.

What is the best way to take care of my teeth?

The key to maintaining healthy teeth throughout your adult life and avoiding toothaches and dental treatments in the future is proper oral hygiene, which should include:

  • Brushing your teeth three times a day, after each meal – this is essential before bedtime and after you get up in the morning, and always using toothpaste that contains fluoride.
  • Using interdental brushes or dental floss every day after toothbrushing helps to eliminate plaque and the subsequent appearance of dental tartar.
  • Using mouthwash after each toothbrushing. Mouthwashes are a big help when it comes to maintaining good oral health and preventing diseases and infections, as well as minimising problems such as halitosis or bad breath, which affects a significant part of the population.
Does Laboratorios KIN conduct experiments with animals?

No. Fortunately, EU law forbids the use of animals in studies on the safety and effectiveness of cosmetic products and their component ingredients.

Alternative methods not involving animals are used to assess the safety and effectiveness of Laboratorios KIN’s current products and products in development.

What does the caption “0% Alcohol” mean on the product labelling?

Are Laboratorios KIN's oral care products suitable for diabetics?

Do Laboratorios KIN's oral care products contain animal-derived ingredients?

No. Laboratorios KIN’s oral care products are not formulated with animal-derived ingredients, so they can safely be consumed by vegans and vegetarians.

Why do Laboratorios KIN's oral care products contain parabens?

Products that are used in the oral cavity must be harmless and always free of any microbiological contamination. Therefore, at Laboratorios KIN we believe that parabens are the most suitable preservatives due to their proven effectiveness and their long history of being safe and harmless. This is why we add them to our products, to prevent the development of pathogenic microorganisms and the resulting potential risk to the consumer.

There are currently no other substances available with the same safety profile and a preservative efficacy comparable to that of parabens.

Leaving aside certain commercial considerations which, unfairly and in breach of the current EU regulations*, lead to many products being labelled as “parabens-free” in order to give the impression that these are harmful or artificial ingredients, the truth is that parabens are extremely safe and they are naturally found in barley, strawberries, peaches and carrots, among other types of food.

*Regulation (EU) No. 655/2013 on common criteria for the justification of claims used in relation to cosmetic products.
