Oral and Dental Health

Improving oral and dental health

For many people, oral and dental health are associated with clear routines: brushing teeth, flossing, and regular dental check-ups. At the same time, the mouth is a complex system in which teeth, gums, saliva, and numerous bacteria interact. This interplay influences how stable the tooth enamel remains, how sensitive the gums react, and whether issues such as bad breath or recurring irritation occur.

What does oral health mean?

In research, the oral cavity is increasingly viewed as its own ecosystem: The so-called oral microbiome includes a great diversity of microbial species that organize themselves in biofilms on the teeth, tongue, and mucous membranes. Oral health encompasses more than cavity-free teeth. In everyday life, it primarily describes a stable balance of:

• intact tooth enamel,
• low-irritation gums,
• good saliva quality, and
• an oral flora that remains stable under changing conditions.

When this balance shifts, typical signs often appear: cavities, sensitive tooth necks, coated tongue, irritated gums, or recurring gingivitis. In this context, scientific papers often speak of "resilience": A healthy oral microbiome is able to absorb stresses, such as sugar phases, stress, or short-term changes in oral hygiene, and then return to a more stable state. The Rosier working group describes mechanisms that can prevent dysbiosis and which factors promote stability.

The most important levers in everyday life – consistent and individually appropriate oral hygiene

Good oral hygiene can be reliably implemented through regular routines:

• brushing teeth twice a day, ideally with proper technique and appropriate pressure,
• daily interdental care, for example with dental floss or interdental brushes,
• tongue care, if coating or bad breath are an issue,
• regular dental check-ups and prophylaxis.

Many people underestimate that not only "whether" but "how" you brush is crucial: pressure, brushing duration, angle at the gum line, and the order in the routine influence how effective the care is in the long term.

Fluoride and tooth enamel

Fluoride is an established component in the context of dental care because it supports the mineral balance of the tooth enamel and is firmly anchored in many guidelines for caries prevention. Fluoride is therefore classified by experts as a useful addition to the daily toothpaste routine, without having to make a "miracle cure" out of it.

Diet: Frequency is often more important than individual foods

For the oral flora, it is not only "sugar yes or no" that is relevant, but often the question: How often is food eaten and drinks consumed throughout the day? Frequent snacking or small amounts of sweet drinks keep the environment in a state unfavorable for tooth enamel and biofilm for longer. A randomized study by Lundtorp-Olsen et al. examined, for example, how short-term sugar stress affects the salivary microbiota and what changes become measurable.

In everyday life, this does not mean that everything must be strictly avoided. Often, it is more helpful to group sugar times, plan enough breaks between meals, and choose drinks more consciously.

Gums as a point of orientation

Gums often react early: bleeding during brushing, redness, or swelling can be indications that the routine or technique should be adjusted or that a professional assessment is advisable. In research, it is also relevant that periodontal germs and inflammatory processes are not only viewed locally, but also discussed in connection with systemic issues. Bui et al., for example, describe associations between periodontal pathogens and various systemic diseases in review articles.

Probiotics and oral health: What is being investigated?

The term Probiotics Oral Health is frequently searched because many people are interested in the idea of viewing microbial balance not only through "removal" by brushing, but also through targeted microbial approaches. This field is broad scientifically: Reviews describe studies on probiotics in areas such as biofilm composition, gingivitis and periodontitis parameters, or bad breath, but at the same time emphasize that results depend heavily on the strain, dosage, form of application, and study design.

Kilian et al. provide a detailed overview of the diversity of the oral microbiome and explain why biofilm ecology, saliva, pH value, and diet are central influencing factors. Kaźmierczyk-Winciorek et al. additionally discuss immunological mechanisms being researched in this context and classify the current state as a developing field of research.

Another frequently cited framework comes from general microbiome research: Reid et al. describe how microbial communities can return to more stable states after disturbances, partly through natural recovery, partly in the context of complementary approaches.

Dietary supplements and dental health: Classify instead of overhype

The basis for dental health remains a balanced diet and stable oral hygiene. Complementary products are often discussed when the diet is one-sided or certain living circumstances, such as stress phases or highly variable routines, make constant supply difficult.

For all complementary strategies, the following applies: The selection should be transparent, for example regarding ingredients, dosages, and form of application. Expectations should remain realistic. Oral health is a systemic issue and rarely depends on a single building block.

Bad breath: A common topic with multiple causes

Bad breath often arises not "only" from teeth, but from a combination of biofilm, tongue coating, saliva flow, and diet. Typical factors in everyday life are:

• tongue coating and biofilm,
• dry mouth, for example due to stress, certain medications, or low fluid intake,
• food residues in the gaps,
• irritated gums.

In this case, clarification by a doctor or dentist is recommended to get to the exact cause.

When professional clarification is advisable

Everyday optimization is helpful, but there are situations in which a dental check-up is particularly advisable:

• severe or persistent gum bleeding,
• pain that wakes you up at night,
• visible defects or sensitivities, for example in cases of suspected cavities,
• recurring gingivitis or suspected periodontitis,
• loose teeth or significant changes in the bite.

Research: Why the oral microbiome receives so much attention

From a scientific point of view, the oral microbiome is also interesting because it is easily accessible and provides a lot of information about microbiological patterns. Lim et al. describe the oral microbiome as a possible reservoir for biomarkers in the context of various oral and oropharyngeal diseases. This research shows above all how differentiated the field is: Microbiome data are not interpreted in isolation, but viewed in conjunction with clinical parameters and risk factors.

FAQ – Answers to frequently asked questions

Which probiotics support oral and dental health?

In studies and reviews, certain strains from the genera Lactobacillus and Bifidobacterium are primarily investigated in the context of the oral flora. For example, Lactobacillus reuteri is frequently mentioned in various studies and settings, as well as Lactobacillus salivarius. What is important: The results of probiotic preparations depend heavily on the strain, dosage, form of administration, for example a lozenge, direct granules, or chewing gum, and the initial situation. Anyone interested in this can look for a clear strain designation, consumption recommendation, and duration of use on products. A good oral hygiene, consisting of tooth brushing and interdental care, always remains the basis.

Can probiotics positively influence the oral microbiome?

Researchers are investigating whether probiotic strains can influence the composition of the oral flora or certain parameters, for example biofilm characteristics. In a randomized study, for example, it was examined how the salivary microbiota and inflammatory markers change under short-term "sugar stress" and how probiotics can be incorporated into this. At the same time, the results overall are not "universal" because the oral microbiome is very individual and many factors play into it, including diet, oral hygiene, saliva flow, smoking, and medications. Therefore, studies usually allow us to infer that something is being investigated, not that it will turn out the same for every person. It is useful to view probiotics as a possible complementary approach and to keep expectations realistic.

What is the difference between DentaSan ProbioGUM and ProbioPROTECT?

DentaSan ProbioGUM is a sugar-free chewing gum with a selected bacterial strain, Lactobacillus salivarius SGL03.

DentaSan ProbioPROTECT is a direct granule or stick, also called "Fast-Melt", with three bacterial strains: Lactobacillus salivarius, Lactobacillus rhamnosus, and Bifidobacterium animalis ssp. lactis. In addition, it contains vitamin C, vitamin D3, as well as xylitol. The differences are therefore mainly the form of administration, chewing gum versus granules, the number of strains, 1 versus 3, and the additional ingredients in DentaSan ProbioPROTECT. The application is also different: according to the product info, ProbioPROTECT is usually dissolved in the mouth 1x daily after brushing teeth.

Which bacterial strains support healthy gums?

In the literature, strains such as Lactobacillus reuteri are primarily investigated in studies on gum parameters, for example gingival inflammation or bleeding. Lactobacillus salivarius also appears in oral concepts and product formulations; individual products combine it with other strains such as L. rhamnosus and B. animalis ssp. lactis. What is important: Which results are observed depends heavily on the specific strain, the dose, and the setting, for example additional professional dental cleaning or orthodontics. In everyday life, the basis for gum health remains good plaque control through brushing, cleaning the gaps, and regular check-ups.

From what age are probiotic chewing gums suitable for children?

With probiotic chewing gums, the microbiome issue is less of a sticking point than safety while chewing, especially swallowing. For DentaSan ProbioGUM, it is frequently stated in retailer information that it is not suitable for children under 3 years. In practice, many parents also orient themselves on whether a child can reliably chew gum and spit it out again. This is often more the case in school age, but varies individually.

Which dietary supplements support the prevention of gingivitis?

For prevention, oral hygiene, i.e., brushing and interdental care, as well as professional prophylaxis, are foremost. Dietary supplements are at most a complementary building block. Regarding nutrients, there are approved, clear statements: Vitamin C contributes to normal collagen formation and to the normal function of, among other things, the gums.

For vitamin D, there are approved statements regarding the maintenance of normal body functions such as bones, muscles, and teeth, as well as a normal calcium level. If someone frequently has gum problems, it is useful to also think about the basics: brushing technique, gaps, smoking, sugar frequency, dry mouth, and having persistent complaints checked by a dentist. Probiotic approaches are discussed in research as a possible complement, but are strain- and context-dependent.
