Gums & Prevention

Preventive Dentistry and Home Care

The routine that prevents most dental disease: brushing technique, interdental cleaning, diet and recall visits.

Side-by-side cross-sections of a healthy tooth in pink gum with normal bone, and a tooth with inflamed gum, calculus and lost bone.
Left: healthy gum and bone level. Right: calculus below the gum, a deepened pocket and bone loss — the sequence behind most adult tooth loss.

Daily technique

Brush twice daily for two full minutes using a fluoride toothpaste and a soft-bristled brush held at roughly forty-five degrees to the gumline, using small circular motions rather than a hard back-and-forth scrub. After brushing, spit out the excess toothpaste but avoid rinsing with water immediately, since this washes away the protective fluoride film that continues working on the enamel.

Clean between the teeth once a day with floss, interdental brushes or a water flosser, ideally before brushing so that the fluoride toothpaste can then reach the surfaces that have just been cleared of plaque. A toothbrush alone reaches only around sixty percent of tooth surfaces, leaving the contact areas between teeth, where decay and gum disease commonly begin, untouched.

Fluoride and remineralisation

Fluoride works by strengthening the enamel crystal structure, making it more resistant to acid attack, and by helping to repair very early, microscopic decay before a cavity forms. A pea-sized amount of standard-strength fluoride toothpaste is appropriate for adults and most children over the age of six.

For patients at higher risk of decay, additional professional fluoride varnish applications during check-up visits provide an extra protective boost beyond daily toothpaste use.

Professional recall

A check-up and professional cleaning every six months, or more frequently if recommended based on individual risk, detects decay, cracks, gum pockets and early oral lesions long before they become symptomatic, and at a fraction of the eventual cost of treating an advanced problem.

Radiographs taken periodically during recall visits reveal decay between teeth that cannot be seen or felt during a routine visual examination, which is a major reason why regular attendance matters even when nothing feels wrong.

Diet and decay

Tooth decay is driven far more by how often sugar is consumed than by the total quantity eaten in a day. Frequent sipping of sweetened tea, soft drinks, or repeated snacking throughout the day keeps the mouth in an acidic state for many hours, giving bacteria continuous fuel to produce the acid that dissolves enamel.

Confining sugary foods and drinks to mealtimes, rather than spreading them across the day, gives saliva the chance to neutralise acid and remineralise enamel between exposures. Chewing sugar-free gum after meals can further stimulate helpful saliva flow.

Questions patients ask us

Electric or manual brush?
Oscillating-rotating electric brushes remove modestly more plaque on average, especially helpful for those with limited manual dexterity, but good manual brushing technique performed thoroughly is perfectly adequate for most people.
Is mouthwash necessary?
Mouthwash is a helpful addition for some patients, particularly antimicrobial rinses for gum disease, but it does not replace brushing and interdental cleaning, which physically remove plaque that rinsing alone cannot.
How do I know if I am brushing correctly?
Disclosing tablets, available from a pharmacy, temporarily stain remaining plaque so you can see exactly which areas are being missed, and a dentist or hygienist can also demonstrate technique directly during a visit.

When to see us

Get examined without waiting if any of the following applies to you:

  • Gums that bleed without provocation, or bleeding that has become heavier
  • Teeth that feel loose, are drifting, or gaps that are opening up
  • Persistent bad breath or taste, gum abscesses, or pus on pressing the gum

Chronic Bad Breath Caused by Gum Infection

Chronic bad breath, or halitosis, is frequently driven by underlying gum disease. Subgingival bacteria produce volatile sulphur compounds within periodontal pockets. Effective resolution requires professional periodontal debridement, targeted biofilm disruption, and meticulous daily interdental hygiene rather than cosmetic masking.

Loose Permanent Teeth from Advanced Periodontal Disease

Loose teeth from advanced gum disease occur when severe chronic inflammation destroys the supporting alveolar bone and periodontal ligament. With timely periodontal therapy, splinting, and meticulous plaque control, many loose teeth can be stabilised and preserved without extraction.

Scaling and Root Planing Deep Cleaning Procedure

Scaling and root planing is a non-surgical deep cleaning procedure designed to treat chronic periodontitis. It removes subgingival plaque biofilm, hard calculus, and bacterial endotoxins from tooth root surfaces to arrest active gum disease and prevent bone loss.
