Customisation & Fit
Can I customise my gumshield?
Yes! You can choose from different colours and add full graphic and text customisation.
I want a colour that isn't on your website.
Simply contact us, and we will try our best to get the colour you want.
Will my gumshield feel bulky?
No, our custom-fit gumshields are designed to be slim and comfortable while providing maximum protection. Unlike boil-and-bite gumshields, ours are made to fit perfectly to your unique dental anatomy.
Can I get a gumshield that fits over a retainer?
If you wear a removable retainer, you should take it out before using your gumshield. If you have a fixed retainer, we can make a custom fit for you—just let us know when ordering.
Can I add my name or logo to my gumshield?
Yes, you can add custom text and upload logos during the design process.
Do you offer clear or discreet gumshields?
Yes, we offer clear gumshields for those who prefer a more subtle look.
I have a large or small mouth—will the gumshield fit me?
Yes! Since it's custom-made from your impression, your gumshield will be tailored to your exact mouth size and shape.
Can I get a gumshield if I have missing teeth?
Yes, we can customise your gumshield to accommodate missing teeth. Just let us know in advance so we can adjust the fit.
What if my gumshield doesn't fit properly?
If you feel your gumshield doesn't fit as expected, send us clear images and videos within 14 days, and we'll assess it for a free adjustment or remake.
Will my design look exactly like the preview?
Due to natural variations in dental anatomy, the exact placement and appearance of custom designs may vary slightly from the preview. Your design will be adapted to fit your unique teeth structure for optimal fit and protection.
Do your gumshields cover all my teeth?
Our gumshields cover teeth up to and including the second molars (second back teeth). They do not extend to wisdom teeth. This is the professional standard for sports mouthguards and provides optimal fit, comfort, and protection.
Taking Impressions
How do I take my impression properly?
We provide full step-by-step instructions inside your kit, and you can also watch our tutorial at getpiranha.co.uk/pages/impressions to ensure you get it right the first time.
Will I get assistance if I need help with my impression?
Yes! We have a dedicated WhatsApp helpline where you can send photos or videos of your impression for feedback before sending it back. Our team will guide you through the process if you need any help.
What if I mess up my impression?
If your impression isn't suitable for manufacturing, we'll let you know and send you a replacement kit at cost price. We're not here to overcharge you, just to make sure you get the perfect fit!
How long do I have to take my impression?
There's no strict deadline for taking your impression, but we recommend doing it as soon as possible to avoid delays in receiving your gumshield.
Can I take an impression with my partial denture in?
No, you must remove your partial denture before taking your impression.
Can I use your gumshields with fixed braces?
We recommend waiting until after your braces are removed, as our impression kits aren't suitable for use with braces.
Can children use your impression kits?
We recommend our kits for ages 10 and above, as younger children may find them difficult to use. Contact us if your child is under the age of 10.
Can I take my impression if I have a gag reflex?
Yes! If you have a strong gag reflex, we recommend:
- Tilting your head forward slightly while taking the impression.
- Breathing through your nose to stay relaxed.
- Practicing with an empty tray before mixing the putty to get used to the feeling.
Should I bite down into the putty?
No! You should press the tray up evenly into your teeth—not bite into it. Biting can cause distortion and affect the final fit.
How do I send my impression back?
Once your impression is approved via WhatsApp, we'll give you access to our returns portal, where you can generate a DPD QR code. Simply scan it at your nearest DPD drop-off location, and your package will be sent back to us for free.
Can I track my impression once I send it back?
Yes! Keep hold of your tracking number when you post it so you can track its return to us.
Should I photograph my impression before sending it?
Yes! We strongly recommend taking clear photographs of your impressions and packaging before dispatch. This serves as evidence in the event of courier-related damage or loss.
Ordering & Processing
How do I place an order?
Simply choose your gumshield, customise it (if applicable), and complete checkout. We'll send you an impression kit first, and once we receive your impression, we'll start making your gumshield.
Gumshield or Mouthguard?
They're the same thing! In the UK, gumshield is the more common term, while mouthguard is used more internationally. No matter what you call it, it's designed to do the same job—protect your teeth from impact in sports and combat. At Piranha, we use both terms so you can always find what you're looking for.
How long does the full process take?
- Impression kit dispatched: Same day if ordered before 15:00 GMT, next working day if after.

If you need to change your gumshield type, colour, or any details, contact us as soon as possible. Once production has started, we cannot make changes. Production begins the same working day we receive your impressions if received before 14:00 GMT.
Do I have to pay extra for sending my impression back?
No! We provide a free prepaid return label via our returns portal, so sending your impression back to us is completely free.
Can I cancel my order?
You can cancel within 14 days of receiving your impression kit if it remains unopened and unused. A £25 restocking fee applies. Once the kit is used or impressions are submitted, the order becomes final and non-refundable.
What if I ordered the wrong gumshield?
If you realise you've ordered the wrong type, let us know before sending back your impression so we can adjust your order if manufacturing hasn't started.
Can I send my own impression, model, or STL file?

Can I track my order?
Yes, we notify you at every stage—when we check in your impression, when your gumshield is being made, and when it's shipped back to you.
Can I change my design after ordering?
Your custom design becomes final once you complete checkout. Once production has commenced, we cannot make any changes to colours, text, spelling, or design elements. Please review your design extremely carefully before placing your order.

If your order is taking longer than expected, check your email for any updates. If you need further assistance, contact us at help@getpiranha.co.uk.
Do I need to be home to receive my gumshield?
Your gumshield is shipped via DPD, so you don't need to be home to receive it. DPD allows you to reschedule your delivery, arrange for it to be left with a neighbour or in a safe place, or collect it from a designated pickup shop if needed. You'll receive tracking updates with options to manage your delivery.
What happens if my parcel gets lost?
If your impression kit or gumshield doesn't arrive within the expected timeframe, contact us within 10 days of the estimated delivery date and we'll investigate. If necessary, we'll send a replacement.
Are you responsible if I choose 'leave safe' delivery?
Any 'leave safe' or 'safe place' deliveries authorised by you are entirely at your own risk. Piranha is not responsible for parcels left without a signature that are subsequently lost or stolen.
What if delivery fails or is returned?
Parcels returned to us due to failed delivery, incorrect address, or failure to collect from a pickup point may incur re-shipping charges.
Materials & Safety
What materials do you use?
Our gumshields are made from high-quality EVA (Ethylene Vinyl Acetate), which is:
- Gluten-free
- Vegan-friendly
- Free from toxins
- Durable and impact-resistant for maximum protection
Are your gumshields BPA-free?
Yes, all our gumshields are 100% BPA-free and contain no harmful chemicals, making them completely safe for use.
Do your gumshields contain latex?
No, our gumshields are latex-free, making them safe for anyone with latex allergies.
Are Piranha gumshields CE-certified?
Yes! Our gumshields are manufactured in a GDC-registered UK dental lab and meet CE safety standards for sports protection.
Are your gumshields safe for all sports?
Yes! Whether you play MMA, boxing, rugby, hockey, martial arts, or any contact sport, our custom-fit gumshields provide maximum impact absorption and protection.
Will the gumshield affect my breathing or speaking?

Can I wear my gumshield if I have sensitive teeth?
Yes! Our gumshields are made to cushion impact, reducing strain on your teeth and making them comfortable for those with sensitivity.
Why does my gumshield have varying thickness?
Sports gumshields naturally have variations in thickness throughout to provide optimal protection. High-impact areas (front teeth) are thicker for maximum protection, while other areas are thinner for comfort and breathability. This is a professional design feature and normal in sports mouthguard manufacturing.
How do I care for my gumshield?
Clean your gumshield after each use with cool water and mild soap or a designated mouthguard cleaner. Store it in the provided storage case. Keep it away from direct heat sources and do not expose it to temperatures above 60°C. Never leave it in direct sunlight, hot vehicles, or near heaters.

How long should my gumshield last?
The lifespan depends on frequency of use, intensity of sport, bite force, and care practices. Signs of normal wear include minor surface abrasions and gradual thinning. For athletes in high-impact sports with frequent use, we recommend replacement every 6-12 months or sooner if damage occurs.
When should I replace my gumshield?
You should replace your gumshield if you notice significant wear, visible damage, changes in fit, or after any major dental work. If your gumshield has been exposed to extreme heat, altered, or no longer fits properly, it should be replaced immediately.
