What Both Companies Do Well

Before discussing the differences, it's worth noting that both Sentinel Mouthguards and Pro Teeth Guard provide quality custom dental appliances.

Both companies offer:

• Custom-made night guards fabricated from dental impressions
• Multiple material options for different grinding habits
• FDA-compliant dental materials
• Manufacturing in professional dental laboratories
• Free impression kits
• Lower pricing than many traditional dental offices

If you're currently wearing a store-bought boil-and-bite guard, either option is likely to provide a significantly better fit and improved comfort.

Product Selection

Both companies recognize that one night guard doesn't fit every patient.

Sentinel Mouthguards

Sentinel offers four primary night guard options:

• Comfort Guard – Soft and flexible for light to moderate grinding.
• Hybrid Guard – Soft inside with a durable hard exterior.
• Hard Guard – Designed for moderate to heavy grinding.
• Durability Guard – Extra-thick protection for aggressive grinders.

Sentinel also offers additional specialty products, including daytime guards for clenching, tongue and cheek biting guards, retainers, sports mouthguards, and whitening trays.

Pro Teeth Guard

Pro Teeth Guard offers several custom night guard options as well, including:

• Soft Night Guard
• Hybrid Night Guard
• Hard Night Guard
• Ultra Thin Night Guard

Like Sentinel, these products are intended to accommodate different levels of teeth grinding and clenching.

---

Ordering Process

Both companies make ordering relatively straightforward.

The typical process looks like this:

1. Choose your night guard.
2. Receive an impression kit by mail.
3. Take impressions at home.
4. Mail the impressions back.
5. Your custom night guard is fabricated and shipped to you.

For many customers, this process eliminates the need for multiple dental appointments while still providing a professionally made appliance.

Digital Scan Compatibility

One area where Sentinel offers additional flexibility is digital dental scans.

Many dental offices now use intraoral scanners such as iTero®, TRIOS®, Medit®, and other digital systems. If you've recently had dental work or orthodontic treatment, there's a good chance your dentist already has a digital 3D scan of your teeth.

Rather than taking new impressions, Sentinel allows customers to upload compatible digital scan files after placing an order. This can simplify the process while eliminating the need to make impressions at home.

If you don't already have a digital scan, Sentinel also offers the same traditional impression kit process used by many online night guard companies.

---

Materials and Manufacturing

Both companies use professional dental laboratory manufacturing rather than mass-produced retail products.

Sentinel emphasizes hand-finishing each appliance before shipment, including:

• Trimming
• Polishing
• Quality inspection
• Final fit review

Pro Teeth Guard similarly manufactures custom appliances using dental laboratory techniques and professional-grade materials.

For most buyers, both companies represent a significant step up from over-the-counter mouth guards available at pharmacies.

---

Warranty and Satisfaction Guarantee

A night guard is only valuable if it fits properly.

Both companies recognize this by offering satisfaction guarantees.

Sentinel

Sentinel's 100-Day Satisfaction Guarantee allows multiple opportunities to achieve the correct fit through adjustments or remakes if needed. Depending on the situation, customers may also receive a complimentary replacement impression kit to improve the final result.

Warranty coverage depends on the guard selected:

• Comfort Guard – 6 months
• Hard Guard – 1 year
• Hybrid Guard – 1 year
• Durability Guard – 1 year

Pro Teeth Guard

Pro Teeth Guard offers a 60-Day Satisfaction Guarantee and product warranties that vary by model, with many guards carrying one year of coverage.

Both companies stand behind their products, although their guarantee structures differ slightly.

---

Pricing

One reason online custom night guard companies have become increasingly popular is affordability.

Many dental offices charge anywhere from $400 to $800—and in some cases even more—for a custom night guard.

Both companies offer professionally fabricated custom night guards at prices that are often significantly lower than those charged by many dental offices.

While pricing varies depending on the specific model selected, both companies offer significant savings compared to traditional dental practices.

---

Customer Support

Customer service is often overlooked until something doesn't fit quite right.

Sentinel places considerable emphasis on working directly with customers throughout the adjustment process if modifications are needed.

Pro Teeth Guard also offers customer support and guidance throughout ordering and after delivery.

The best choice may depend on whether you value additional adjustment opportunities or prefer a straightforward return process.

---

Which Company Should You Choose?

Both companies have earned positive customer reviews and manufacture quality custom night guards.

Sentinel Mouthguards may be the better choice if you:

• Already have a digital dental scan.
• Want the option to skip traditional impressions.
• Prefer multiple opportunities for adjustments if necessary.
• Want several guard styles designed for different grinding habits.
• Are interested in additional products like daytime guards or tongue and cheek biting guards.

Pro Teeth Guard may be a good fit if you:

• Prefer a traditional impression kit process.
• Want a straightforward ordering experience.
• Are already familiar with their product lineup.
• Value their satisfaction guarantee and warranty structure.

Frequently Asked Questions

Are Sentinel and Pro Teeth Guard both custom-made?

Yes. Both companies manufacture custom night guards based on your dental impressions rather than selling one-size-fits-all appliances.

---

Can I use a digital scan instead of impressions?

Sentinel accepts compatible digital dental scan files from many intraoral scanners, making it possible for some customers to skip the impression process. If you don't already have a scan, you'll simply complete the included impression kit.

---

Are online custom night guards as good as dentist-made guards?

Many online companies use professional dental laboratories and high-quality materials similar to those used for dentist-made appliances. The biggest difference is often the ordering process and overall cost.

---

Are custom night guards worth it?

For people who grind or clench their teeth regularly, a properly fitted custom night guard generally provides better comfort, retention, and durability than a boil-and-bite guard purchased at a pharmacy.

---

Final Thoughts

Both Sentinel Mouthguards and Pro Teeth Guard offer professionally manufactured custom night guards that provide an affordable alternative to many dentist-made appliances.

If you're looking for a traditional impression-kit experience backed by a solid satisfaction guarantee, Pro Teeth Guard is a reputable option.

If you value additional ordering flexibility—including the ability to use an existing digital dental scan—along with multiple guard styles and a comprehensive fit-adjustment process, Sentinel Mouthguards offers several advantages that may make it the better choice for your needs.
