Night guards, bonding or same-day crowns: choosing the right treatment for tooth wear

According to the 2023 Adult Oral Health Survey, 71% of dentate adults in the UK have some degree of tooth wear (tooth surface loss). That is not a niche problem affecting a small group of patients: it is the majority of adults sitting in dental chairs up and down the country, many of whom may be entirely unaware anything is wrong. Tooth wear frequently progresses without symptoms, often for years, before sensitivity or a visible change in appearance finally prompts someone to seek advice.

At Bellevue Dental in Wandsworth Common, identifying and managing tooth surface loss is part of daily clinical life. Patients come in with sensitivity they have dismissed as normal, or teeth that have gradually flattened without them noticing. The condition is common, but it is not inevitable, and the right intervention at the right time makes an enormous difference to long-term outcomes. This article covers the three types of wear, the warning signs to catch early, the prevention steps that actually work, and the treatment options available — from a simple night guard through to same-day crowns.

What tooth wear actually means: the three types explained

Tooth wear is not a single condition. It is a collective term for the cumulative loss of mineralised tooth structure caused by chemical and mechanical forces. UK clinical guidance recognises three distinct categories, and understanding the difference between them is not academic pedantry: it directly determines which prevention strategy and which treatment option is appropriate.

In real patients, two or all three types frequently overlap. Accurate diagnosis before any treatment decision is therefore essential, because treating the wrong cause will not stop the progression.

Dental erosion: chemical loss from acids

Dental erosion is the dissolution of enamel and dentine by non-bacterial acids. Those acids are either dietary (fizzy drinks, citrus fruit, vinegar-based foods, sports drinks) or intrinsic, meaning gastric acid from reflux or frequent vomiting. Erosive tooth wear produces a characteristic smooth, cupped or hollowed appearance on affected surfaces. Patients with gastro-oesophageal reflux disease (GORD) often show the most pronounced changes on the palatal surfaces of upper front teeth, where stomach acid repeatedly contacts the enamel.

Attrition and abrasion: wear from mechanical forces

Dental attrition is tooth-to-tooth contact wear, most commonly driven by bruxism-related grinding during sleep or habitual daytime clenching. It tends to flatten cusps symmetrically and produces a polished, faceted appearance on biting surfaces. Dental abrasion, by contrast, is wear caused by external objects or materials: the most common culprits are overly aggressive toothbrushing, hard-bristled brushes and highly abrasive toothpastes. Abrasion leaves a distinct pattern, typically wedge-shaped notches at the gum margin rather than the generalised flattening seen with attrition.

Early warning signs of tooth wear

Most patients dismiss the early signs of tooth surface loss as normal ageing. By the time dentine exposure and sensitivity prompt a visit, moderate wear has usually already occurred. Recognising the signs earlier, before restorative intervention becomes necessary, is where patients can genuinely protect themselves.

What you can spot yourself

The most self-detectable signs are teeth that appear shorter, flatter or more translucent at the edges; increased sensitivity to cold, hot or acidic food and drink; and a yellowing of tooth colour as the dentine beneath the enamel becomes more visible. Notches or indentations near the gum line are also worth noting. Sensitivity is often the first symptom that sends someone to a dentist, which is why understanding the other visual cues matters: they appear before the discomfort does, and catching them earlier keeps treatment simpler.

How a dentist assesses the extent of wear

The main UK screening tool for tooth surface loss is the Basic Erosive Wear Examination (BEWE). Each sextant of the mouth is scored from 0 to 3 based on the worst-affected surface, and the cumulative score across all six sextants guides clinical decisions. A score of 0 to 2 warrants monitoring and preventive advice; scores of 3 to 8 indicate low risk with ongoing observation recommended. Scores between 9 and 13 indicate moderate severity requiring closer review and additional fluoride measures; a score of 14 or above signals severe wear and the need to consider restorative intervention. BEWE is a chairside screening tool that can be completed within a routine appointment.

The causes behind most cases of tooth wear

Understanding what is driving a patient’s wear is not optional background information: it determines both the prevention strategy and the treatment choice. The evidence hierarchy here is clear, and being honest about it helps patients prioritise the changes that will actually slow progression rather than focusing effort on secondary factors.

Acidic diet and gastric reflux

Frequent consumption of acidic food and drink is the single strongest evidence-based driver of erosive tooth wear, particularly when it occurs between meals when saliva flow is at its lowest. Prolonged contact time amplifies the risk significantly: sipping a fizzy drink slowly over an hour is far more damaging than drinking the same amount in one sitting. The specific mechanism matters because it changes the advice: frequency and contact time are more important than the total volume consumed. For patients with GORD or a history of frequent vomiting, controlling intrinsic acid exposure is a key component of management and often requires medical assessment; a GP referral for diagnosis and ongoing management is an important clinical step alongside any dietary changes.

Bruxism and toothbrushing habits

Bruxism-related wear is a real and clinically significant contributor, but the evidence for it as a primary driver of erosive progression is weaker than for dietary acids. It is better understood as a cofactor: it compounds existing erosive damage and accelerates the loss of already-softened enamel rather than causing erosion independently. Toothbrushing abrasion follows a similar pattern: brushing immediately after acid exposure, using a hard-bristled brush, or applying excessive force all accelerate surface loss, but they are secondary to the acid exposure itself in terms of overall significance for progression.

Proven steps to slow or stop the damage

Behavioural change is the foundation of any management plan. Restorative outcomes are substantially improved when underlying causative behaviours are controlled; without addressing the cause, restorations carry a higher risk of failure. The steps below are practical and grounded in evidence rather than blanket restriction.

Dietary changes and reflux management

The most effective dietary change is reducing the frequency of acidic food and drink rather than eliminating it entirely. The practical rule: consume acidic drinks in one sitting rather than sipping over an extended period, and use a straw to reduce direct contact with tooth surfaces. After acid exposure, rinsing with water is advisable; brushing should wait at least 30 to 60 minutes to avoid abrading softened enamel. For patients experiencing symptoms of reflux, such as heartburn, regurgitation or a sour taste, a GP consultation is the right first step, because controlling the acid source is more effective than any purely dental intervention.

Correct brushing technique and fluoride

A soft-bristled brush, a low-abrasion fluoride toothpaste containing at least 1,450 ppm fluoride, and a gentle circular or modified Bass technique are the core recommendations for adults. Where active erosive wear or dentine sensitivity has been identified clinically, higher-concentration fluoride toothpaste or remineralising agents containing hydroxyapatite or CPP-ACP can be used as additional support, though the evidence base for remineralising agents varies and professional guidance should be sought. Twice-daily brushing remains one of the most evidence-based behavioural interventions for protecting tooth surfaces, particularly when technique is consistent and correct.

Night guards for grinding and clenching

A custom-made hard acrylic occlusal splint does not stop the grinding habit itself, but it protects tooth surfaces and any existing restorations during sleep by distributing the forces of bruxism across a removable appliance rather than directly onto enamel. Over-the-counter options often fit poorly and may be less effective than professionally made devices; professional assessment is recommended to ensure correct fit and appropriate design. When attrition is the dominant wear pattern, a professionally fitted night guard is typically the first clinical recommendation before any restorative work is considered.

Restorative options for tooth wear: choosing the right approach

The guiding principle in current UK guidance is to be as conservative as possible: adding to existing tooth structure rather than removing more of it. Severity, the underlying cause and the amount of remaining tooth structure together determine which restorative option is appropriate. Jumping straight to crowns without addressing the cause first is not good clinical practice, and it is not the approach taken at Bellevue Dental.

Composite bonding as a first-line restorative approach

Direct composite bonding is the first-choice restorative option for moderate tooth wear because it is conservative and repairable, and the process can often be reversed if needed. It can restore lost enamel on anterior teeth and rebuild worn posterior cusps, often without anaesthetic or tooth preparation. Survival data suggest annual failure rates of around 2 to 3% in well-managed cases, with many restorations remaining functional for five or more years. The caveat is straightforward: longevity depends heavily on controlling the underlying cause. Unmanaged bruxism or an ongoing acidic diet significantly shortens the lifespan of any composite work, regardless of how well it was placed.

Porcelain onlays, veneers and full-coverage crowns

When wear is more extensive, or when direct restorations have failed repeatedly, indirect restorations become the appropriate step. Ceramic onlays and overlays cover more extensive wear on posterior teeth with good longevity and strength, while veneers address anterior aesthetic concerns where enamel is severely thinned. Crowns are the right choice when remaining tooth structure is significantly reduced, when full cusp coverage is needed for structural reasons, or when previous restorations have not held. At Bellevue Dental, in-house same-day crown technology means the entire process, from digital scan to fitted crown, is completed in a single appointment, eliminating the need for a temporary crown and a second visit. As with all restorative options, the underlying cause should be managed in parallel to support long-term outcomes.

Conclusion

Tooth wear is common, progressive, and largely manageable when it is caught and addressed at the right stage. The 2023 Adult Oral Health Survey figures make clear that this is not a rare problem: it affects the majority of UK adults to some degree. The right treatment depends entirely on the type and severity of wear, the underlying cause, and the amount of tooth structure remaining. No single option fits every patient.

The prevention priorities are consistent across cases: address dietary acid frequency first, seek medical management for reflux if it is present, use fluoride correctly and consistently, and wear a professionally fitted night guard if bruxism is contributing. Where restorative work is needed, starting with the most conservative effective option and working up from there is the evidence-based approach. If you have noticed sensitivity, visible changes to your teeth, or simply want a clearer picture of your oral health, an assessment at Bellevue Dental in Wandsworth Common is the clearest next step you can take.
