BioGaia® Prodentis for
Gum Problems

Sufferers of Gum Problems

Three out of four adults suffer from gum problems during their lifetime. Gum problems occur among adults and is more common among the elderly, diabetics, pregnant women, individuals that smoke and individuals that take certain medication. Gum problems are due plaque buildup at the gum-line. Plaque is bacteria that needs to be removed regularly, otherwise it will harden into tartar which can only be removed by your dentist or dental hygienist.

Bacterial Balance

There are more than 700 bacterial species that protect the mouth against bacteria that form plaque and cause problems. When the balance among oral bacteria is disrupted due to inadequate oral hygiene, stress and/or poor diet, plaque-containing bacteria can gain the upper hand and cause gum problems.

Symptoms of Gum Problems

Healthy gums are pink, firm and fit tightly to each tooth. Signs of gum problems are redness, soreness and bleeding of the gums, especially after brushing. Additionally, bad breath can be a sign of gum problems. Ask your dentist or dental hygienist if you are unsure if you have gum problems.

Tips and Advice

Start in Time

There is a lot you can do yourself, and a lot that your dental hygienist or dentist can help you with. The important thing is that you start on time, have patience and spend a few minutes each day with your oral care routine.

Visit Your Dentist and Hygienist Regularly

It is important to have regular visits to your dental professionals that check your mouth for early detection of gum problems. It is recommended that you visit your dentist and dental hygienist twice per year. A dental hygienist performs a professional cleaning to remove tartar and will give you advice on how to maintain your oral care between visits.

Avoid Stress and Smoking

Both stress and smoking can contribute to gum problems. The body’s immune system is affected by both of these factors which will reduce gingival defense. Ask your dental professional for advice if you need help to quit smoking.

Don’t Forget Your Daily Oral Hygiene

It is important to brush your teeth thoroughly twice a day for at least two minutes each time. It is also important not to brush too hard – your teeth will not become cleaner with increased pressure. In addition to brushing, you are strongly encouraged to clean between the teeth with dental floss, a tooth stick or interdental brushing. Cleaning between your teeth should be done before brushing, since the plaque will be removed then brushed off.

Incorporate Lactic Acid Bacteria

In addition to visiting your dental professionals and daily oral care, supplementation of lactic acid bacteria may be an option. There are specific strains of lactic acid bacteria that have shown in clinical studies to be able to maintain a balanced bacterial flora in the oral cavity. Lactic acid bacteria can act as a great complement to the daily oral care routine.
