The number of brushing modes and the number of intensity levels are not the same thing. Pressure sensors also differ: some use a red light to warn of excessive pressure, others vibrate, and some also distinguish the right amount of pressure. Start with an alert you can easily notice every day, then check replacement-head compatibility and pack prices to clarify your choice.
Why consider it now
When buying your first electric toothbrush or replacing an existing handle, consider everyday controls and the terms for buying consumables alongside feature names. Modes, intensity settings, and replacement-head compatibility differ even within the same brand, so this comparison uses configurations sold in Korea in 2026-10.
Why this order
The iO5 is our first suggestion for visually checking appropriate pressure while choosing among 5 modes. The 5300 moves up in priority if 2 intensity levels and handle and replacement-head costs matter more. Choose the 3100 HX4031/21 for 3 intensity levels and lower upfront cost, the iO2 Black for excessive-pressure warnings and 2 modes, or the 5500 for separate Clean and Whitening modes. This order is not calculated from manufacturers’ cleaning-performance figures or nationwide sales rankings.
Oral-B
Oral-B iO5
Our first pick
Choose modes while keeping track of brushing pressure
We recommend it at rank 1 for its ability to indicate appropriate pressure and its choice of 5 modes. The rank-2 5300 offers 2 intensity levels and a lower handle price, while the iO5 provides more detailed pressure guidance. Conversely, if intensity adjustment and replacement-head costs matter more than a range of modes, choosing the 5300 first is reasonable.
Suitable for people who want to monitor brushing pressure while choosing among several cleaning modes.
A pressure alert can simply prompt you to ease off when you press too hard, or it can help you find the right amount of force. The iO5 has a pressure sensor that distinguishes light, appropriate, and excessive pressure, along with 5 brushing modes. It is a suggestion for anyone who wants both pressure guidance and a choice of modes.
The modes are Daily Clean, Intense Clean, Sensitive, Super Sensitive, and Whitening. Mode names alone do not promise therapeutic effects or the same cleaning results for everyone. The separately sold iO Ultimate Clean Black OR63 replacement heads cost KRW 25,130 for a pack of 2, equivalent to KRW 12,565 per 1 head. This is the listed price for that option on 11st on 2026-10-24, excluding additional card discounts and reward accrual.
A reference for adjusting pressure
It distinguishes appropriate and light pressure as well as warning about excessive pressure. The alerts provide a reference for anyone who wants to adjust their brushing force.
A broader choice of modes
Its 5 modes include separate Sensitive and Super Sensitive settings. This matters if you want a choice rather than 1 fixed brushing action.
Before you choose
It requires iO-specific replacement heads and cannot share standard Oral-B PRO heads. Factoring in the total purchase cost of replacement heads warrants another look at the cost difference from the 5300.

Philips
Philips Sonicare 5300 HX7101/05
Why consider it
When 2 intensity levels matter more than the mode count
We recommend it at rank 2 for its 2 intensity levels and verified price of KRW 99,000. It suits people who prefer adjusting intensity within the same cleaning mode to the iO5’s 5 modes. It offers 1 fewer intensity level than the 3100 HX4031/21, but we prioritize its C3 package, replacement reminder with compatible genuine RFID heads, and manufacturer-stated use of up to 21 days. Consider the 3100 first if upfront cost and 3 intensity levels matter more.
Suitable for people who want a lower handle price while retaining control over cleaning intensity.
A toothbrush does not need many modes to offer adjustable intensity. The black HX7101/05 provides 1 cleaning mode with 2 intensity levels. It is a straightforward configuration for anyone who wants to select intensity while keeping the same cleaning action.
It alerts you to excessive pressure through vibration and structures brushing with a section prompt every 20 seconds and a 2-minute timer. The basic package contains 1 handle, 1 C3 brush head, and 1 charger. The separately sold W2 White HX6066/14 pack of 6 was listed on 11st at KRW 42,900 on 2026-10-24, equivalent to KRW 7,150 per 1 head. This replacement-head product includes free standard shipping, with an additional KRW 3,000 for Jeju or remote islands and mountainous areas. Since that total buys 6 heads together, it is important not to confuse the checkout total with that of a pack of 2 iO replacement heads.
Choose intensity within the same mode
Select between 2 intensity levels within 1 mode. This lets you distinguish between adding modes and changing intensity when making your purchase.
Brush-head replacement reminder
It tracks the usage count and intensity of genuine RFID-equipped brush heads and uses an LED to indicate when replacement is due. This feature requires a compatible genuine RFID brush head.
Before you choose
The 5500 is a better fit if you want separate Clean and Whitening modes. Pressure guidance uses vibration, making it a different consideration from the iO5’s distinction between pressure states.

Philips
Philips Sonicare 3100 HX4031/21
Why consider it
Lower upfront cost with 3 intensity levels
We recommend it at rank 3 for its 3 intensity levels and listed handle price of KRW 84,900. Including KRW 3,000 standard shipping, the KRW 87,900 total is KRW 11,100 below the 5300 at KRW 99,000 with free shipping. We place the 5300 first for those who value its included C3 head, replacement reminder with compatible genuine RFID heads, and manufacturer-stated use of up to 21 days. If upfront cost and intensity choice take priority, the 3100, with manufacturer-stated use of up to 14 days, can be the first choice.
Suitable for people who want to select cleaning intensity while reducing the initial purchase cost.
The 3100 HX4031/21 offers 3 intensity levels within 1 cleaning mode. It suits people who want to adjust intensity within the same mode rather than switch between several cleaning modes. It alerts you to excessive pressure through vibration, with 30-second section prompts and a 2-minute timer to divide brushing time.
The official basic package contains 1 handle, 1 Optimal White W brush head, and 1 USB charger, with a DC5V rating. The manufacturer states up to 14 days of use on a full charge. It accepts click-on brush heads, so check the attachment type and pack size when buying replacements separately. The listed price of KRW 84,900 plus KRW 3,000 standard shipping totals KRW 87,900. The retailer also separately lists KRW 4,000 for Jeju and KRW 3,000 for remote islands and mountainous areas.
3 intensity levels within the same mode
Choose among 3 intensity levels within 1 cleaning mode. This is useful for people who want more intensity choices rather than additional modes.
Vibration alerts for excessive pressure
If you press too hard, vibration prompts you to reduce pressure. You can also refer to 30-second section prompts and a 2-minute timer while brushing.
Before you choose
Consider the 5300 first if its C3 package and replacement reminder with compatible genuine RFID heads matter more. Manufacturer-stated maximum use is 14 days for the 3100 and 21 days for the 5300.

Oral-B
Oral-B iO2 Black
Why consider it
Start with excessive-pressure warnings and 2 modes
We recommend it at rank 4 for people who want to start with excessive-pressure warnings and 2 modes. Choose it for a red light and reduced speed under excessive pressure rather than the iO5’s distinction between light, appropriate, and excessive pressure. At KRW 102,000, it costs less upfront than the KRW 149,000 5500, so we place it first, but consider the 5500 first if separate Clean and Whitening modes matter more. It uses the same iO replacement heads, so the handle price alone does not establish the lowest long-term cost.
Suitable for people who prioritize simple controls and excessive-pressure warnings over a variety of modes.
For the iO2 sold in Korea, the officially listed number of modes varies by color. The Black model selected here has 2 modes, Daily Clean and Sensitive, and is distinguished from the White model, which is listed with 1 mode. It is worth considering if you prefer operation through a single-touch button.
When excessive force is detected, the rotation speed decreases and a red light comes on. Section prompts every 30 seconds and a 2-minute timer also help you divide brushing into sections without continually tracking the time yourself. The separately sold iO Ultimate Clean Black OR63 replacement heads cost KRW 25,130 for a pack of 2, equivalent to KRW 12,565 per 1 head. This is the listed price for that option on 11st on 2026-10-24, excluding additional card discounts and reward accrual.
Automatic response to excessive pressure
The speed decreases and a red light comes on when you apply too much force. A warning indicator accompanies a change in operation.
A timer for dividing brushing into sections
It provides prompts every 30 seconds and a 2-minute timer. These can help allocate brushing time so you do not stay in just 1 section.
Before you choose
Official guidance for Korea lists 2 modes for Black and 1 mode for White. The cost of iO-specific replacement heads is calculated using the same purchase option as for higher iO models.

Philips
Philips Sonicare 5500 HX7110/03
Why consider it
Separate Clean and Whitening modes rather than intensity choices
We recommend it at rank 5 for people who need separate Clean and Whitening modes. It has 1 more mode than the 5300 but less intensity choice, so we do not treat it as a straightforward upgrade. Its KRW 149,000 upfront cost exceeds the iO2 Black’s KRW 102,000, but preferring Clean and Whitening modes on a sonic toothbrush can reverse their order. We suggest the 5300 or 3100 first for people who would use intensity adjustment more often than a Whitening mode.
Suitable for people who want separate Clean and Whitening modes on a sonic toothbrush rather than a choice of intensity.
The number 5500 can make it tempting to assume it includes every feature of the 5300. The HX7110/03 offers 2 modes, Clean and Whitening, but only 1 intensity level. Consider it if you prefer separate cleaning modes to increasing or decreasing intensity.
It includes vibration alerts for excessive pressure, section prompts every 20 seconds, and a 2-minute timer. The official basic package for the white HX7110/03 contains 1 handle, 1 C3 brush head, and 1 charger. It can use the separately sold W2 White HX6066/14 pack of 6 also considered for the 5300. With a listed price of KRW 42,900 on 11st on 2026-10-24, equivalent to KRW 7,150 per 1 head, the 2 handles can be compared using the same replacement-head purchasing conditions. This replacement-head product includes free standard shipping, with an additional KRW 3,000 for Jeju or remote islands and mountainous areas.
Separate modes for different purposes
It provides Clean and Whitening as separate modes. These 2 distinct actions are useful if you want to choose by mode name.
Maintenance with compatible brush heads
It accepts W2 replacement heads through a click-on attachment. The replacement reminder requires compatible genuine RFID-equipped brush heads.
Before you choose
With only 1 intensity level, it is less suitable than the 5300 for people who need 2 levels. When buying the same W2 replacement heads, a difference in handle price does not translate into a difference in ongoing maintenance costs.
