Tooth Erosion and the Impact of Acid in the Food and Drink We Consume

The Unseen Battle in Our Mouths Every time you sip or bite, there’s a hidden tug of war in your mouth, determining the fate of your teeth. Dental health isn’t just about routines but also the substances we expose our teeth to. While most of us are conscious of sugar’s role in tooth decay, many overlook another silent adversary: acid.

Basics of Tooth Enamel

1. Australia’s Natural Defences and Our Own: In Australia, we’re no strangers to the importance of defence against the elements. Much like our need for sun hats or sturdy umbrellas, our teeth have their own protective shield: enamel.
2. The Marvel of Enamel: This remarkable substance is the hardest in our body, tougher even than our bones. Its primary role? To defend teeth from the daily battles of biting, chewing, and temperature extremes. The enamel’s translucent nature also bestows our teeth with their characteristic sheen.
3. Limitations of Enamel: However, enamel has its Achilles heel. Unlike other tissues, once it’s lost, the body can’t regenerate it. This non-renewable nature of enamel makes its preservation paramount.

What is Tooth Erosion?

1. Beyond the Cavity: A Wider Threat While cavities often steal the limelight in dental discussions, a subtler and broader threat lurks: tooth erosion. Unlike cavities that focus on decayed spots, erosion paints with a broader brush, stripping away the protective enamel layer.
2. The Australian Dental Association’s Warning: The ADA has been vocal about this rising menace. Their studies point towards a growing trend of tooth erosion, alarmingly more so among the younger Australian population. It’s not just about sweets but also the pH level of what we consume.
3. Erosion vs. Wear: A Crucial Distinction It’s essential to differentiate between tooth wear and erosion. The former stems from mechanical actions (think grinding). The latter, erosion, is a chemical reaction primarily instigated by the acid present in what we eat and drink.

The Role of Acid in Tooth Erosion

1. The pH Playground: A Quick Recap To understand acid’s role, it’s pivotal to revisit the pH scale, which spans from 0 (highly acidic) to 14 (highly alkaline). Neutral, sitting at the midpoint, is 7. The natural environment of our mouth hovers just above this neutral mark.
2. Demineralisation: Enamel’s Undoing Introducing acidic foods and drinks shifts the balance, dipping the oral pH below neutral. This acidic environment beckons a process known as demineralisation. Enamel, in its essence, houses essential minerals like calcium and phosphate. An acidic milieu leaches these away, leaving enamel vulnerable.
3. Saliva: The Unsung Hero But nature, in its wisdom, provides a counter. Our saliva. This natural concoction works tirelessly, neutralising the acid and aiding in the remineralization process. But there’s a catch: constant exposure to acid can overwhelm our salivary defence, letting demineralisation hold sway.

Common Culprits: Acidic Foods and Drinks

1. Everyday Items with a Sour Side: It’s surprising how many of our regular foods and drinks come with an acidic punch. While some might be expected, others can be more deceptive.
2. The Usual Suspects: Citrous fruits like lemons, oranges, and grapefruits are renowned for their tartness. Fizzy drinks, even the diet ones, and certain fruit juices also contain acid levels high enough to affect our teeth.
3. Hidden Acidic Offenders: But there are silent culprits too. Did you know that certain sports drinks, often perceived as healthy, can be acidic? Similarly, wines, particularly white wine, can subtly erode your enamel over time.

Other Sources of Acid in the Mouth

1. When the Body Plays Tricks: While most would link acidic foods and beverages to tooth erosion, the body can sometimes be its own worst enemy.
2. Reflux and Oral Health: Gastroesophageal reflux disease (GERD) isn’t just about heartburn. When stomach acids find their way into the mouth, they can wreak havoc on the enamel.
3. Medication Missteps: Some medicines, especially certain syrups or chewable vitamin C tablets, can be acidic. Coupled with the potential of some medications to reduce saliva flow, it’s a double jeopardy for dental health.
4. The Dry Mouth Dilemma: Xerostomia, commonly known as dry mouth, isn’t just discomforting. Reduced salivary production means less neutralising power against acids, elevating the risk of tooth erosion.

Signs and Symptoms of Tooth Erosion

1. Spotting the Invisible enemy’s: Tooth erosion begins discreetly but can escalate if not detected early. Knowing what to watch out for is half the battle.
2. Early Warning Signs: Yellowing teeth can be one of the first signs, as the underlying dentin becomes exposed. You might also notice a particular shine, a hallmark of eroded surfaces.
3. Advanced Symptoms: As erosion intensifies, the shape and texture of teeth can change. Cracks, chips, and indentations on the surface become more frequent. Moreover, as enamel thins, sensitivity to hot and cold intensifies, making ice cream and hot coffee a challenge.

Preventive Measures

1. Proactivity: The Best Approach: The age-old adage prevention is better than cure, rings true, especially in the case of tooth erosion.
2. Smart Consumption Habits: Drinking acidic drinks through a straw can minimise tooth exposure. Moreover, it’s wise to delay brushing for at least 30 minutes after consuming acidic foods or drinks. Brushing immediately can spread the acid, intensifying its impact.
3. Regular Dental Check-Ups: Routine check-ups at your local dental clinic can help identify early signs of erosion, allowing for timely interventions.
4. Strengthening the Fortress: Embracing products fortified with fluoride can bolster enamel resilience. Fluoridated toothpaste and mouthwashes are readily available, and they’re instrumental in the fight against demineralisation.

Restorative Solutions for Advanced Tooth Erosion

When Prevention Isn’t Enough Despite our best efforts, sometimes the forces against our enamel win out. But all hope isn’t lost. Modern dentistry provides a range of solutions to restore the form and function of teeth affected by erosion.

1. Dental Bonding: This procedure involves applying a tooth-coloured resin to the affected tooth. It not only conceals the damage but also offers protection against further erosion.
2. Veneers and Crowns: For more severe cases, porcelain veneers or crowns can be a solution. These act as shields, covering the entire front surface (veneers) or the whole tooth (crowns) to restore its appearance and strength.
3. The Role of Fillings: When erosion affects the tooth’s cusp or chewing surface, fillings can come to the rescue. Modern filling materials mimic natural enamel’s colour and strength, offering both aesthetics and protection.
4. The Journey to Holistic Dental Health: Our dental health isn’t solely defined by our brushing habits or the occasional dental visit. It’s a cumulative result of our lifestyle choices, from what we eat and drink to how we care for our teeth post-consumption.

With tooth erosion becoming a growing concern among Australians, understanding the role of acids in our diet is essential. By being informed and proactive, we can not only ward off the early signs of erosion, but we can also seek timely treatments should the need arise.

It’s all about striking a balance between enjoying our favourite foods and drinks and ensuring our teeth remain strong and healthy for the long haul.
