Oral-B Electric Toothbrush Heads: Complete Guide

Oral-B Brush Head Compatibility Chart

Standard Oral-B Brush Heads

Standard Oral-B brush heads use a snap-on attachment system that has been consistent for over 20 years. This means any standard head you buy today will fit Oral-B models going back decades. There are several types, each designed for specific needs:

CrossAction

The CrossAction is Oral-B's most popular and versatile brush head. Its bristles are angled at 16 degrees to the tooth surface, allowing them to reach into gaps between teeth and along the gumline more effectively than straight bristles. This is the default head included with most Oral-B models and the one we recommend for everyday use. It provides excellent all-around cleaning for most people.

FlossAction

The FlossAction head features MicroPulse bristles — thin, flexible bristles interspersed between the standard ones — designed to reach deeper between teeth and mimic the action of flossing. While it does not replace actual flossing, it provides better interdental cleaning than the CrossAction. This is a good choice if you struggle with plaque buildup between teeth.

Sensitive

The Sensitive head uses extra-soft bristles that are gentler on teeth and gums. It is designed for people with sensitive gums, receding gumlines, or those recovering from dental procedures. The softer bristles still clean effectively but with significantly less irritation. If you experience bleeding gums with standard heads, try switching to Sensitive.

3D White

The 3D White head features a polishing cup in the center surrounded by standard bristles. The cup holds toothpaste against the tooth surface longer during brushing, enhancing surface stain removal from coffee, tea, wine, and other staining substances. Results are gradual — expect weeks of regular use before noticing whiter teeth.

Precision Clean

The Precision Clean is the classic, round Oral-B head with a simple bristle arrangement. It is effective and affordable, often available at lower prices than specialized heads. A solid no-frills choice for everyday brushing.

Ortho

Designed specifically for braces, the Ortho head features bristles arranged to clean around brackets and wires effectively. The center row of bristles is trimmed shorter to fit around orthodontic hardware, while the outer bristles clean the tooth surface normally. Essential for anyone with fixed braces using an Oral-B electric toothbrush.

iO Series Brush Heads

The iO brush head system launched with the iO Series in 2020 and uses a completely different magnetic attachment. iO heads snap into place with a satisfying magnetic click and are designed to work specifically with the linear magnetic drive motor, ensuring optimal energy transfer to the bristle tips.

iO heads are available in fewer varieties than standard heads: iO Ultimate Clean (similar to CrossAction), iO Gentle Care (similar to Sensitive), iO Radiant White (similar to 3D White), and iO Targeted Clean (for focused interdental cleaning). The selection continues to expand as the iO lineup matures.

Cost Comparison

Replacement brush head cost is a significant ongoing expense that should factor into your toothbrush purchasing decision. Here is what to expect annually:

When to Replace Your Brush Head

Oral-B recommends replacing brush heads every 3 months. Signs it is time for a replacement include:

• Blue indicator bristles have faded to white — Most Oral-B heads have blue bristles that gradually bleach as they wear. When they are mostly white, it is time to replace.
• Bristles are frayed or bent — Splayed bristles cannot clean effectively and may irritate gums.
• You have been sick — Replace after illness to avoid reintroducing bacteria.
• Reduced cleaning feeling — If the brush feels less effective, a new head usually solves it.

Using a worn brush head can reduce cleaning effectiveness by up to 50% according to some studies. Regular replacement is one of the easiest ways to maintain your electric toothbrush's performance.

Third-Party Brush Heads

Third-party manufacturers produce compatible replacement heads for standard Oral-B handles at significantly lower prices — often $2-4 per head. Popular brands include Pursonic, NEVADENT, and various Amazon marketplace sellers. Quality varies considerably; some are nearly identical to genuine Oral-B heads, while others have inferior bristle quality or poor fit.

For iO models, third-party options are less common but emerging. If you choose third-party heads, look for brands with strong reviews and avoid the cheapest options, as poorly made bristles can be too harsh on gums or fall out during use.
