There are three ways to buy a mouthguard in Hong Kong and about a tenfold difference in price between the cheapest and the dearest. Most people either overpay for protection they do not need, or buy the cheap one at the pharmacy and stop wearing it by the third session.
This is what is actually available here, what it costs, and how to work out which one you need.
The three options
1. Stock guards — the pharmacy option
Pre-formed, no moulding, sold in a blister pack. They arrive one shape and stay that shape.
Avoid them. A stock guard does not conform to your teeth, so it moves under impact and you have to bite down to keep it in place — which is exactly what you cannot do when someone is talking to you or you are breathing hard. Most people who own one stop wearing it. The cheapest guard is the one you do not wear.
2. Boil-and-bite — the sensible default
Softened in hot water and moulded to your own teeth at home. This is what almost every club and school player in Hong Kong wears, and for good reason.

The important distinction inside this category is single-layer versus double-layer. A single layer compresses on the first heavy contact and does not recover, so it stops protecting long before it looks worn out. A double-layer guard has a firmer outer layer to spread the force and a softer inner layer to hold the fit. The price difference is small; the difference in protection is not.
3. Custom-fitted from a dentist
Made from an impression or a 3D scan of your teeth. The best fit available, the thinnest profile for the protection given, and by a distance the most expensive route.
Worth it if you take contact several times a week, if you have had dental work you are protecting, or if you compete at a level where a lost tooth is a real career cost. Not worth it for a child whose teeth are still moving — the guard stops fitting as the mouth changes.
What it costs here
Verify these figures before publishing. The SafeJawz price is ours. The OPRO figure comes from a Hong Kong stockist listing and should be confirmed. The Decathlon, SISU and dental-clinic figures need checking against current local pricing — do not publish a price you have not seen this month.
| Option | Typical Hong Kong price | Verdict |
| Stock guard, pharmacy | Low | Skip it |
| Boil-and-bite, single layer | Low | Fine for occasional use, replace often |
| Boil-and-bite, double layer | From around HK$220 | Where most players should land |
| Premium boil-and-bite (OPRO Silver, Platinum) | Around HK$379 at HK stockists | Good guards, priced at a premium |
| Custom from a dentist | Significantly higher — get a quote | For serious or frequent contact |
Where to buy in Hong Kong
Decathlon — the widest cheap range, physical stores across the city, and you can try sizing in person. Their own-brand guards are entry level; treat them as a starting point rather than a season’s protection. Browse Decathlon, you can also buy Pillar Sports tapes products on Decathlon!
Escapade Sports and Streamline Sports — both carry OPRO, both ship locally, both aimed at the rugby market. If OPRO is the brand you want, they are the straightforward route. Browse Streamline Sports.
Pillar Sports — that is us. We distribute SafeJawz in Hong Kong, hold stock here, price in Hong Kong dollars and ship by SF Express. We also supply clubs and schools directly, which is worth a conversation if you are kitting out a squad rather than one player.
Your dentist — for custom guards. Ask for a quote before committing; prices vary considerably between clinics in Hong Kong.
Carousell and marketplace listings — a mouthguard is a personal-hygiene item that sits in someone’s mouth. Buy it new.
Ordering from overseas — OPRO, SISU and most of the DTC night-guard brands will ship to Hong Kong, but you are paying in GBP or USD and waiting on international post. Check whether a local stockist carries the same model before you do.
The brands you will actually see
An honest read on each. We sell one of these, so weigh that accordingly.
OPRO. The strongest brand in this market and the one most Hong Kong rugby players know. Official mouthguard of England Rugby and Wales Rugby Union, and their Instant Custom-Fit line genuinely narrows the gap to a dental guard. They are good products at a premium price, and they are widely stocked here. If budget is not a constraint and you want the safest-known name, this is it.
SafeJawz. What we distribute. Double-layer construction, developed with dentists, junior and senior sizing, ortho versions for anyone in braces, and a case with every guard. Cheaper than the OPRO equivalents. The Marvel range is licensed superhero styling, which is a selling point for a nine-year-old and irrelevant to a 30-year-old — the guard underneath is the same either way. Buy SafeJawz.
SISU. Very thin profile with a distinctive perforated design, popular with people who cannot tolerate bulk. Divisive: some people rate them highly, others find the thinness unconvincing. Harder to find in Hong Kong than OPRO.
How to fit a boil-and-bite guard
Most people rush this, and a rushed mould is the main reason a decent guard feels bad.
- Boil the kettle, then let the water stand for 30 seconds. Straight off the boil is too hot and can over-soften the material.
- Submerge the guard for 20–30 seconds. Not longer.
- Lift it out, shake off the water, and test the temperature against your lip before it goes near your teeth.
- Seat it over the upper teeth and bite down firmly. Then suck in, and press the guard against your teeth and gums with your tongue and fingers for a further 20 seconds.
- Drop it into cold water to set.
If the fit is wrong, repeat it. The material re-moulds. If it still will not seat after a second attempt, you have the wrong size.
Looking after it in this climate
Hong Kong humidity is genuinely hard on mouthguards. A guard that goes back into a case damp, into a kitbag, in August, will grow something.
Rinse in cold water after every session, let it air-dry fully before it goes in the case, and keep the case ventilated. Never leave it in a car or on a windowsill — heat warps the mould permanently. Replace it when the bite impressions flatten out or the edges start to split, which for anyone training two or three times a week means about once a season.
So which one should you buy?
- Playing school or club sport, once or twice a week: a double-layer boil-and-bite. Anything more is over-buying.
- Training in a combat gym several times a week: the same, replaced more often — or a custom guard if you are competing.
- Wearing braces: an ortho model, and mention it to your orthodontist.
- Buying for a child: junior sizing, boil-and-bite, and expect to replace it as they grow. A custom guard is wasted on a mouth that is still changing.
- Competing at a level where your teeth are part of your livelihood: see a dentist.
For most people reading this, the honest answer is a double-layer boil-and-bite guard that fits properly and gets worn every session. Which sport you play changes the details — we have broken that down here.
