Visible Pressure Sensor

Everyone’s felt the urge to brush with fervor and stick the bristles right up against the surface of your teeth. However, you’re not doing your teeth nor those bristles a favor. Vigorous brushing can wear down your enamel and shorten the lifespan of your bristles.

What is a pressure sensor?
A pressure sensor, with respect to electric toothbrushes, are small components inside the brush handle that detect when you are applying too much force during your brushing routine.  When it detects the use of excessive pressure, the brush will reduce the amount of power delivered to the brush head in order to reduce the chances of ongoing damage to the teeth and gums.  If the excess force is removed, the motor will power back up to a fuller speed and perform as normal. This change can happen within split seconds.

The bristles of the brush should skim the tooth surfaces to sweep away, bacteria, food debris and plaque.  Hard and aggressive brushing will not normally help, hence the pressure sensor to alert you to these instances where you do apply too much force.

Visible Pressure Sensor

The Visible Pressure Sensor is an important feature of higher end Oral-B models that score high points. Pressing too firmly with a toothbrush causes tooth abrasion. This is where the toothbrush starts to remove the enamel of a tooth and can lead to gum recession and tooth sensitivity.

Oral-B’s Visible Pressure Sensor not only reduce the motor power but will alert the user by switching on a light on the brush, quite often a red warning light found at the top of the brush handle.  This comes on as soon as too much pressure is detected.  It remains on until such time as the pressure is reduced.

App Tracking with Bluetooth
The most advanced Oral-B model will change the motor speed, illuminate a warning light whilst also sending a message to your smartphone application which is tracking your tooth cleaning.  These Bluetooth enabled brushes will often log the amount of time too much pressure was applied for and use it as a way of coaching you to achieve better oral health.

Pressure Sensor – Electric Toothbrush Features – How Important?

Some Oral-B models have Pressure Sensing but without the Visible warning light on handle
The brush has a sensor built in that will slow down the power of the brush motor if you are brushing with too much force. This is good as it helps protect the teeth and gums. The motor will speed up again, if the pressure is reduced/stopped.

However, it does not have what we really call a true pressure sensor. Aside from a very slight change in sound there is no way to alert you that you are brushing too hard. It does not have a red light, that turns on to alert you, like other brushes from Oral-B with a built in pressure sensor.

Oral-B Smart Series 6500

The Smart Series 6500 is effectively a glorified Oral-B Pro 6000 with a an additional bonus electric toothbrush handle. Think buy one get one free.

If you need two electric toothbrush handles for the family, the Oral-B Smart Series 6500 is the most economical way to do it and offers great value for money. The electric toothbrush handles themselves are top of the range electric toothbrush handles that offers a great range of features for a cheap price.

Effectively this Oral-B Smart Series 6500 is 2 x Oral-B pro 6000 electric toothbrush handles being sold together at a discounted price.

Oral-B Smart Series 6500 Features

5 Cleaning Modes – The primary reason many people opt to spend a little more for the Smar tSeries 6500 is for the multiple cleaning modes available to suit your needs, and for a more rounded cleaning experience.

  1. Daily Clean is the default mode for regular cleaning.
  2. Pro Clean operates at a higher frequency for more extensive cleaning when needed.
  3. Sensitive is gentler on your teeth to avoid pain, but still allows you to clean your teeth sufficiently.
  4. Whitening allows you to polish your teeth and can be used occasionally or daily.
  5. Gum Care provides a gentle massaging effect on the gums to stimulate blood flow and improve gum health.

Bluetooth Compatibility
Just one of aspects that makes this toothbrush so smart is it’s Bluetooth compatibility. It allows you to connect to the Oral-B app on your smartphone or tablet so you can learn more about your oral cleaning routine and brushing habits, and informs you of ways to improve them. While the app is geared toward the higher end ‘Genius’ line of Oral-B toothbrushes, it can still be helpful in letting you know the battery life, what mode you are in, when you are brushing too hard and more. It also saves data of the last 20 brushes automatically and syncs it when you open the app again.

Smart Wireless Guide

Smart Wireless Guide
In addition to being able to connect to your smartphone, included is a small white, wireless guide that can be placed on a shelf or stuck to a wall. It seamlessly connects to the 6000 brush handle and will let you know how long you have been brushing for, if you apply too much pressure (a sad face will appear), as well as what brushing mode you have selected. This latter point is important as there isn’t a clear indicator on the toothbrush itself and many people may not choose to use the app.

Visible Pressure Sensor LED
One issue that many people have with toothbrushes in general is that they use too much pressure which can cause damage to gums and tooth enamel. The Smart Series 6500 features an easy-to-see LED on the reverse side that flashes in red when too much force is applied as a warning. Additionally, the toothbrush will reduce power temporarily whilst in daily clean, pro clean and sensitive cleaning modes.


QuadPacer
The Smart Series 6500 vibrates every 30 seconds to let you know when to move from one corner of your mouth to the other. While this is a common feature on Oral-B electric toothbrushes, the 6500 also has a green LED indicator that lights up as well to let you know when to change positions, and yellow when the recommended two minutes of brushing is up. This is the same LED that lets you know when you use too much pressure.

Battery Life
The Oral-B Smart Series 6500 uses a Ni-MH (nickel-metal hydride) battery which many won’t be overly pleased with. The reason being is that lithium-ion is so much more effective these days at holding a charge for longer, and without fading. Some of their other higher end series lite Genius toothbrushes use lithium-ion. Having said that, the 6500 still provides around 40 minutes of power on a single charge, which is enough for around 10 days of charging if you don’t keep it on the dock. While this isn’t as much as some of their other models or its competitors, it does a little extra power for the accent lighting and Bluetooth.

One issue with Ni-MH batteries in particular is that its recommended to let the batteries run down before fully charging to maintain the life of the battery. For this reason you may want to consider the Genius 9000 model which is more advanced, and uses lithium-ion.

One Charger
The small white charging dock is the same used by almost all Oral-B electric toothbrushes, though you can also choose to attach it to the included brush head holder. These chargers are very easy to clean with just warm water and a cloth.

Battery and Charging Indicator
The 6000 brush handle has a green three stage battery LED indicator at the bottom which is helpful in letting you know just how much juice is left. When the battery is depleted and needs to be recharged, the light will flash red. It’s worth noting that it’s recommended to charge the toothbrush for around a day before using it, even if though you’ll be tempted to test it right away.

Replacement Brush heads
As with all the Oral-B Range, the Oral-B Pro 6500 is compatible with all the Oral-B Brush heads . My particular favourite is the Cross action brush head because of the angulation of the bristles and the small size of the brush head.
