The pH Balance of Your Mouth: Why It Matters
Your mouth’s pH level significantly impacts your dental health. A neutral pH of 7.0 is ideal, while anything below 5.5 becomes dangerously acidic, triggering enamel demineralisation and increasing cavity risk. Studies show the bacteria responsible for gum disease thrive in acidic environments, while beneficial bacteria prefer neutral conditions.
The pH in your mouth fluctuates throughout the day. After eating sugary or acidic foods, pH levels can drop dramatically, creating an environment where harmful bacteria flourish and produce even more acid in a damaging cycle.
To maintain healthy pH levels:
Rinse with water after acidic foods or drinks
Chew sugar-free gum to stimulate saliva production
Wait 30 minutes after eating before brushing
Use alkaline-promoting toothpaste
Regular professional cleanings also help manage oral pH by removing acid-producing plaque buildup.
The Anatomy of Taste: How Your Dental Health Affects Flavour
Your ability to enjoy the full spectrum of flavours is closely linked to your oral health. Taste buds on your tongue detect basic flavours—sweet, salty, sour, bitter, and umami—but your complete taste experience relies on much more.
Saliva plays a crucial role, dissolving food particles and carrying them to taste receptors. Dry mouth conditions can significantly diminish taste perception by reducing this essential function. Additionally, while the tongue identifies basic tastes, your sense of smell contributes substantially to what we perceive as “flavours” through a process called retronasal olfaction.
Oral infections, gum disease, and even certain dental materials can interfere with normal taste function. Bacteria buildup on the tongue can physically block taste buds, while inflammation from infections can alter taste perception at a cellular level.
Maintaining excellent oral hygiene—brushing, flossing, tongue cleaning, and regular dental checkups—helps ensure your taste sensations remain vibrant and accurate. Proper hydration further supports optimal saliva production, enhancing your ability to enjoy every delicious bite.
Breathing & Oral Health: The Surprising Connection
Did you know your breathing habits directly impact your dental health? Mouth breathing, especially during sleep, reduces saliva flow—nature’s way of protecting teeth and neutralising acids. This dryness creates an environment where cavity-causing bacteria thrive.
Chronic mouth breathing also alters facial development in children, potentially leading to narrow dental arches, crowded teeth, and misaligned bites that require orthodontic intervention later.
Nasal breathing, by contrast, filters air through nasal passages, humidifies incoming oxygen, and allows proper tongue positioning against the roof of the mouth. This positioning naturally expands the dental arch during development and creates proper space for adult teeth.
Simple techniques to encourage nasal breathing include:
Practicing conscious nasal breathing during the day
Using gentle saline rinses to clear nasal passages
Working with specialists to address structural issues like enlarged adenoids
Proper breathing is fundamental to both oral health and overall wellness.
