April is one of the best times of year to take stock of what your practice actually has, what it actually needs, and what has been quietly expiring on a shelf since last fall.
Spring marks the start of a busier patient season for most practices. School schedules shift, patients who delayed care over the winter start booking, and procedure volume tends to pick up. Going into that stretch understocked, or stocked with the wrong things, creates pressure that is easy to avoid with a little proactive planning.
According to the ADA Health Policy Institute's practice economics data, supply overhead is one of the top cost concerns for US dental practices, with most spending between 5 and 7% of collections on supplies annually. A spring audit is one of the most practical tools available for keeping that number in check while ensuring your team has everything, they need to deliver great care through the busy season ahead.
Why April is the right time for a supply audit
Most practices do their biggest restocking push at year end, when budgets reset and tax considerations drive purchasing decisions. But a lot can shift between January and April. Usage patterns change, products run low faster than expected, and items ordered in bulk at year end may be approaching expiry.
An April audit catches those gaps before they become problems. It also gives you a clear picture of what you actually use versus what you thought you would use, which makes your next major order smarter and more cost-effective. For practices seeing higher patient volume this spring due to access programs or pent-up demand, a proactive restock is even more important.
Category 1: PPE and infection control
PPE is the highest-turnover category in most dental practices and the one most likely to catch you short without warning. It is also the category most directly tied to your compliance obligations under state infection control guidelines.
What to audit:
- Glove inventory by size. Check that you have adequate stock across all sizes used in your practice, not just the most common ones. Size gaps are one of the most common PPE stockout scenarios and one of the most disruptive to clinical workflow.
- Mask supply and rating. Confirm you have the right masks for both routine care and aerosol-generating procedures (AGPs).
- Surface disinfectants. Check volume and expiry dates, and confirm current EPA approval status.
- Barrier supplies. Check film, sleeves, and covers for all applicable equipment.
What to look for:
- Any products approaching expiry in the next 60 to 90 days.
- Size gaps in glove inventory.
- Products substituted during past shortages that were never formally reviewed for compliance.
Category 2: Restorative and operative supplies
Composite, bonding agents, cements, and matrix systems are procedure-critical and often have shorter shelf lives than practices realize. Bonding agents in particular can degrade in ways that are not always visible. A product that looks fine may have lost efficacy if stored improperly or used past its expiry.
According to Dental Economics, restorative materials are consistently among the highest-waste categories in dental supply spending, largely because practices over-order on shades they use infrequently and under-order on the ones they use every day.
What to audit:
- Composite shades. Are all commonly used shades adequately stocked, and are less frequently used shades nearing expiry?
- Bonding agents and primers. Check expiry dates carefully.
- Temporary cements and materials. Often overlooked until a procedure requires them.
- Matrix bands, wedges, and sectional matrix systems.
What to look for:
- Expired or near-expiry materials that need to be replaced.
- Shades or products discontinued by the manufacturer.
- Items consistently running low, signaling that par levels need adjusting.
Category 3: Hygiene and preventive supplies
Spring is a natural influx period for hygiene appointments as patients catch up on care delayed over the winter. Make sure your hygiene operatories are fully stocked before the rush. Running out of prophy paste or saliva ejectors mid-hygiene day is a disruption that is entirely avoidable.
What to audit:
- Prophy paste. Check quantity and flavour variety if your practice offers patient choice.
- Scalers and curettes. Assess condition and flag any instruments that need sharpening or replacement. Instruments that have been in rotation past their optimal lifespan affect clinical efficiency and patient comfort.
- Fluoride treatments and varnishes.
- Saliva ejectors, HVE tips, and disposable prophy angles.
- Patient take-home kits if your practice provides them.
What to look for:
- Instruments that have been in rotation long enough to affect performance.
- Take-home kit supplies depleted over the winter without a restock.
- Fluoride varnish supply relative to your anticipated patient volume for April and May.
Category 4: Radiography and imaging supplies
Digital imaging has reduced consumable volume for many practices, but there are still supply-dependent components worth reviewing, particularly barriers and positioning devices, which tend to be ordered reactively rather than proactively.
What to audit:
- Sensor sleeves and barriers for digital sensors.
- Positioning rings and holders. Check for wear and breakage.
- Traditional film if your practice still uses it for specific applications.
- Lead aprons and thyroid collars. Check condition and confirm they are within service life.
What to look for:
- Barriers ordered in insufficient quantity relative to daily patient volume.
- Positioning devices that have degraded and are affecting image quality or patient comfort.
Setting par levels: the practical follow-up to any audit
An audit without follow-through on par levels is just an inventory count. The real value of a spring audit is using what you find to set baseline stock levels that reflect actual usage, not estimates.
For each category, the process is the same: calculate average monthly usage, determine your reorder lead time from your primary supplier, and set a par level that keeps you from running short between orders. For high-turnover items like gloves and prophy paste, a 60-day supply on hand is a reasonable target. For lower-velocity items like specialty cements, 30 days may be sufficient.
Frontier Dental carries over 40,000 products across 100+ brands, with free shipping on most orders, which makes it easier to maintain tighter par levels without worrying about order minimums cutting into the economics of more frequent restocking.
Audit ownership: who should run this?
In most practices, the office manager or lead dental assistant owns supply ordering, but the audit itself benefits from clinical input. Dentists and hygienists are best positioned to flag products that are underperforming, approaching expiry, or no longer the preferred option for their procedures.
A structured audit checklist, reviewed by both the clinical and administrative lead, takes less than two hours and pays for itself quickly in reduced waste and fewer emergency orders.
Frequently asked questions
How often should a dental practice do a supply audit? Most practices benefit from a formal audit twice a year: once at year end (for budget planning) and once in spring (to catch gaps before the busy season). Informal spot-checks on high-turnover categories like PPE should happen monthly.
What dental supplies expire fastest? Bonding agents, composite resins, impression materials, and some disinfectants have relatively short shelf lives and should be prioritized in any audit. Expiry dates on these products are not conservative estimates; using out-of-date materials can affect clinical outcomes.
How do I reduce dental supply waste? The most effective strategies are setting accurate par levels based on real usage data, standardizing to fewer SKUs where clinically appropriate, and rotating stock so older inventory is used first. Consolidating purchasing with a single supplier can also simplify tracking and reduce over-ordering.
What is a good dental supply budget benchmark? The ADA Health Policy Institute reports that most US dental practices spend between 5 and 7% of collections on supplies annually. If your practice is consistently above that range, a supply audit is one of the most direct tools for identifying where costs can be brought back in line.
