Interdental Cleaning and Why it’s Important for Good Oral Health

Oral health is integral to maintaining overall wellness, but many people neglect one critical part of their oral hygiene routine: interdental cleaning. Unlike brushing, which cleans the large chewing surfaces of the teeth, interdental cleaning focuses on removing debris and plaque from between the teeth and below the gum line.

This important step in your at-home oral hygiene routine reduces the risk of dental diseases, maintains oral health, and ensures a confident, healthy smile.

Understanding Interdental Cleaning

Interdental cleaning refers to cleaning between the teeth using specialized tools like dental floss or interdental brushes. These tools reach places that toothbrushes can’t, especially the small spaces between teeth and along the gum line.

Dental plaque, a sticky film of bacteria, constantly forms on and between your teeth. If it isn’t removed daily, it can harden into tartar and lead to tooth decay and gum disease.

Importance of Interdental Cleaning

Interdental cleaning effectively removes plaque and food debris between teeth and the gum line, preventing gum disease, tooth decay, and maintaining fresh breath. It complements regular brushing and professional cleanings to ensure comprehensive oral hygiene. Reasons to clean between your teeth include:

Prevention of Gum Disease

Regular interdental cleaning helps prevent periodontal diseases such as gingivitis and periodontitis. These conditions arise from plaque buildup, which, if left untreated, can cause inflammation and potential tooth loss.

Tooth Decay Prevention

Interdental cleaning removes food particles and plaque from between your teeth, areas often missed by brushing alone. These spots can harbor bacteria that lead to cavities.

Fresh Breath

Food remnants, plaque, and bacteria are the primary causes of bad breath. As bacteria break down food, they release foul-smelling volatile sulfur compounds (VSC). Interdental cleaning removes these, keeping your breath fresh.

Preventing Staining

Pigments from foods and beverages can become trapped in plaque, causing enamel staining. By regularly removing plaque, interdental cleaning helps prevent stains, keeping your teeth whiter.

Interdental Cleaning Techniques

Two effective interdental cleaning techniques are dental flossing and interdental brushes:

Dental Flossing

Dental flossing involves using a thin string of nylon or plastic to remove plaque and debris between teeth. Up to 80% of interdental plaque can be removed with flossing.

By gently inserting floss between teeth and below the gum line, moving it back-and-forth, flossing helps prevent decay, gum disease, and bad breath, promoting healthier gums.

Interdental Brushes

Interdental brushes are small, cone-shaped brushes designed for cleaning spaces between teeth. They come in various sizes to accommodate different gaps and efficiently remove plaque and food debris.

By gently moving interdental brushes between teeth in a back-and-forth or rotating motion, these tools effectively remove interdental plaque. Studies show they can be more effective than floss in certain situations, particularly for individuals with braces or wider gaps.

A study comparing interdental brushes to floss found interdental brushes performed better at removing interdental plaque.

Regular Dental Check-Ups

Professional cleanings complement at-home care. Dentists and hygienists use specialized tools to clean areas missed at home and offer personalized advice to improve your interdental cleaning techniques.

Arrange Your Professional Cleaning and Dental Exam

Interdental cleaning is crucial for oral health. Though it may feel like an extra step, it prevents dental issues, leading to healthier teeth and gums and a confident smile.

Combine interdental cleaning with regular dental visits for lasting oral health. Consult with a dentist at Valley Dental Care to assess your interdental health.
