How to Choose your issa™ 4 Collection Electric Toothbrush?

We've come a long way from the ancient chewing sticks and twigs with frayed edges, and the Chinese invention of the classical manual toothbrush made from boar hair attached to bone or bamboo. The first mass production of what we would consider a modern toothbrush began in England in the 1780s, followed by the introduction of the first commercially available toothpaste in a jar, and a few decades later, the tube we know and use today. Still, it took till 1938 to see the first nylon-bristled toothbrush, and crude electric toothbrushes soon after. For the majority of the past century, toothbrushes have remained largely unchanged, until FOREO's issa™ hit the shelves in 2014, fusing sonic-pulse technology with plush silicone.

This new improvement, now in its 4th generation, changed everything, offering the most significant oral care advance in 70 years, with complete, 4-in-1 oral care for teeth, gums, tongue & cheeks in an elegant medical-grade silicone body. A remarkable improvement in battery life allows for up to a full year of brushing on a single charge, and a long-lasting, flexible Hybrid brush head combines ultra-hygienic silicone and PBT polymer, making the brush tough on plaque yet incredibly gentle on the gums. But what is a silicone sonic toothbrush and which one from the issa™ 4 collection is right for you?

What Is a Silicone Sonic Toothbrush?

The best electric toothbrush is, in fact, a sonic toothbrush, because it doesn't rely on abrasive movement to get the job done. It utilizes sonic (high-frequency vibration) technology, which is especially beneficial when combined with soft, hygienic silicone bristles. Silicone bristles may be too gentle on their own. Still, when combined with pulses, they are perfect for comprehensive oral care and more delicate groups, such as babies, young children, individuals with sensory processing difficulties, or those with sensitive teeth and gums.

The benefits of this silicone go far beyond being gentle to gums, helping with gingivitis and periodontal disease, and removing more plaque. Medical grade silicone, like that in the issa™ 4 collection, is also quick-drying, non-porous, BPA and phthalate-free, is easy to sanitize, and resists bacterial growth 10,000 times better than nylon. Even combined with the PBT polymer (in all but the issa™ 4 baby models made of 100% silicone), the brush head will still be 35x more hygienic than a nylon one. To make it seem less like an empty number, imagine your paycheck is 35x more. Does the 35x seem like a big deal now?

Comparing issa™ 4 collection with other electric toothbrushes

Gum health

Equally forgotten in oral health as the scalp is in hair care, gums are the alpha and omega of dental concerns. Healthy gums will mean healthy teeth with far fewer problems. While rotating electric toothbrushes' stiff bristles may give you a clean feel, they can result in overbrushing, damage, and irritation of sensitive gum tissues.

The issa™ 4 collection features a non-rotating brush and boasts soft silicone outer bristles to reduce the risk of gum recession and enamel wear, effectively massaging and protecting. Additionally, issa™ 4 is clinically proven to reduce gingivitis.

Brushing motion

Have you gotten yourself a rotating electric toothbrush and felt weird and awkward as you automatically started your regular manual motion that doesn't work? Did you have to force yourself not to move and let the brush do its job, only to begin feeling passive just standing there? issa™ 4 offers a natural movement, similar to a manual brush, for easy transition to electric toothbrushes or teaching kids the proper movements.
 

Cleaning reach

While regular electric toothbrushes clean only where the bristles reach, ultrasonic or sonic toothbrushes like ISSA 4 use Sonic Pulse technology that channels super-fast vibrations through the silicone and PBT polymer bristles to break down plaque and buildup while creating microbubbles that reach into all the crevices. issa™ 4 is clinically proven to improve overall hygiene by 140%.

Brush head  

The circular and smaller brush heads of other electric toothbrushes require you to spend more time hitting every tooth individually, and some people find them difficult to adjust to. Another minus is wear and tear, as you'll need a new one every 3 months. The issa™ 4 brush head is larger and of a more familiar shape, allowing for more surface coverage per stroke for better cleaning results. Additionally, it only needs to be replaced every 6 months to be cost effective and produce less waste.

Feel and inner peace

A regular electric toothbrush can be aggressive. If you've just opened your eyes, are still unsure what day it is, or are too pre-coffee to process any external input, the last thing you want is a noisy, rough buzzing wakeup call.

issa™ 4 collection is quiet with smooth vibration, working quietly even with braces or dental work. Because indulging yourself does not mean vacations you can't afford, but some spoiled comfort and class in daily life.

Which issa™ 4 collection sonic toothbrush is right for you?

In each category that shows any measurable effect, with criteria set in place (in our case, better oral health), there is the concept of better, worse, and the best. What does the best of this or that even mean? That it does what you want it to for a price you consider a fair investment, that its results within a given parameter surpass those of all similar entities, all while not deteriorating too much in the process, making this success sustainable and scalable in the long term.

issa™ 4 plus: A PRO CLEANING DAILY

You know those people (you may even be one of them) - those hyper-productive, perfectionist A-type personalities who need to do everything at the highest possible level to feel complete and fulfilled. Those who are dead tired from their days of obsessive perfection, and now cannot sleep because the picture of a stray sock caught out of the corner of their eye in the bathroom is burning a hole in their retinas. They/you know they'll get up and fix it before falling into a (semi) restful slumber, because there is so much order to impose onto this chaotic world tomorrow.  issa™ 4 plus is for those people.

It offers a professional dental cleaning every day, along with a complete and personalized experience, because only you know what is truly right for you. Protect the gums, whiten teeth, and keep your mouth feeling fresher for longer. This is the sonic toothbrush that works overtime (It actually doesn't, it has a 2-minute timer). You'll get that post-dentist clean feel you'll constantly explore with your tongue. Be aware, people whom you haven't bragged to about your new toothbrush might interpret that as flirting.

We love:

• AI Pressure Adapt analyzes pressure & auto-adapts intensity so you can never overbrush.
• New modes - deep clean (default), whitening (higher pulsations for discolorated teeth), sensitive (lower pulsations for very sensitive teeth and gums)
• It is clinically proven to improve overall oral hygiene by 140%
• Up to 11,000 high-intensity pulsations/micro-sweeps per minute spanning 16 intensities.
• Travel pouch, perfect to keep your issa™ clean while on the go.

issa™ 4 smile: FULL BUDGET-FRIENDLY ORAL CARE

If you yearn for all those finer things in life but your wallet is sweating bullets every time you try to level up in self-care, screaming and begging you to reconsider, an issa™ 4 smile will make you grin with wallet-approved delight.

With a significantly lower price point than the plus model, it will still deliver on all the key technologies and benefits, maintaining the enviable clinical benefits, such as reducing plaque and improving overall oral hygiene by 140%. An invigorating tooth brushing and gentle gum massage is complemented by a tongue and cheek cleaner on the back, because teeth are just one factor in oral health. It is also excellent for people who have issues with time management and keeping schedules, for teens, or parents of pre-teens who need to control whether their child brushes with a gamified smiley face feature.

We love:

• Battery lasts up to 265 days on 1 USB charge
• Light-up smileys: brush for 2 mins, it smiles; Forget to brush for 12 hrs, it frowns
• 9,000 pulsations per minute
• 4 indicator lights indicate when to move to the next quadrant of the mouth

issa™ 4: FOR THOSE IN DESPERATE NEED OF THEIR DENTIST'S APPROVAL

Tested by real people and their real lives, and approved by dentists, and all who are desperate for their dentist's approval, issa™ 4 is a somewhat stronger and robust model of the previous smile model. It is also the crowd favorite, combining the same advanced Sonic Pulse technology and a unique hybrid brush head as issa™ 4 plus, which lasts twice as long as that of nylon electric toothbrushes.

We love:

• Extreme battery life improvements mean up to 1 year of regular brushing on a single USB charge
• Clinically proven to improve overall oral hygiene by 140% in just 1 month
• Tongue and cheek cleaner at the back
• Clinically proven to remove 30% more plaque than your regular manual toothbrush
• New modes - deep clean, whitening, sensitive
• Clinically proven to reduce gingivitis & 100% of testers report whiter teeth
• App-connected for radical feature adaptability
• Travel pouch, perfect for keeping your toothbrush clean while on the go

issa™ 4 baby: THE CHEWABLE, INDESTRUCTIBLE DOUBLE-SIDED BRUSH

If you've ever tried brushing your young child's teeth, you've realized that a woman scorned has nothing on them. Hell hath no fury like a child you're forcing to do something they don't feel like doing. They will wiggle, cry, fidget, spit, and test your patience to the limit, until you question all of your life choices. Oh yes, and chew! They will chew anything in their path, especially when the teething pains begin.

issa™ 4 baby is made of 100% medical-grade silicone and features soft yet sturdy bristles on both sides, suitable for any toothless or first tooth chews. Significantly improved from the previous generation, this time the brush head is detachable, allowing you to reuse the same brush for all your children (unless trying to brush the teeth of your firstborn has deterred you from pursuing this multi-child path).

We love:

• One less thing to worry about every day
• Massage massages gums to clean & soothe teething pain, and Brush Mode effectively cleans baby's 1st teeth
• It is ideal for kids 0-3
• One brush head lasts for a full year
• Smile helpers make brushing fun and give a little game-like feel in the form of a smiley and frowny face
• Up to 10,000x more hygienic than conventional nylon bristle brushes
• Velvety soft but strong enough to resist sharp baby shark teeth
