Yes, biting someone is assault. Every U.S. state treats a deliberate bite as either assault, battery, or assault and battery, and the charge can range from a misdemeanor to a serious felony depending on how badly the victim was hurt, whether the biter intended harm, and whether disease exposure was involved. Because human bites carry unusually high infection risk and can cause permanent disfigurement, prosecutors and courts tend to treat them more seriously than people expect.
Why a Bite Counts as Assault or Battery
Traditional legal definitions separate the two terms. Assault means causing someone to reasonably fear imminent physical harm; battery is the actual unwanted physical contact that causes injury.1Law.Cornell.Edu. LII Wex Assault and Battery A bite involves physical contact, so it fits squarely within battery. Many states have folded both concepts into a single “assault” statute, so the same incident might be charged as assault, assault and battery, or battery depending on the jurisdiction.
The label matters less than the outcome. Whichever term the local code uses, deliberately sinking your teeth into another person and causing injury is a crime. The real question in any biting case is not whether it is illegal but how heavily the law will come down on the person who did it.
Misdemeanor or Felony: What Moves the Charge Up
The line between a misdemeanor and a felony usually turns on the severity of the injury and the circumstances around the bite.
Simple assault covers bites that cause minor injuries: bruising, shallow cuts, or scrapes that do not require significant medical treatment. Most jurisdictions classify simple assault as a misdemeanor, and this is where most biting incidents land, particularly when the bite happened in the heat of the moment and left no lasting harm.
Aggravated assault applies when the bite causes serious injury, including deep lacerations, significant scarring, tissue loss, or infection requiring hospitalization. Several other factors can also push a charge from simple to aggravated: biting a child, an elderly person, or a law enforcement officer; biting during the commission of another crime; or biting someone while knowingly carrying a communicable disease. Aggravated assault is a felony in every state.
Injury severity carries real weight here because human bites are more dangerous than most people assume. Although they account for only about 3% of bite injuries seen in emergency departments, human bites carry an outsized risk of complications: deep tissue infection, infectious tenosynovitis, septic arthritis, abscesses, necrotizing fasciitis, and in extreme cases, amputation.2NIH. Human Bites – StatPearls – NCBI Bookshelf Bites to the hands, nose, and ears are especially difficult to treat and often require plastic surgery. A bite that looked minor at the scene but developed into a serious infection can support aggravated assault charges even if the defendant did not intend that level of harm.
Disease exposure is a separate escalator. Some states have specific statutes making it a distinct or enhanced crime to expose someone to HIV, Hepatitis B, or Hepatitis C through physical contact, including biting. In those states, a person who bites while knowing they carry a transmissible disease can face felony charges carrying years in prison even if the wound itself was minor. Where no specific disease-exposure statute exists, the transmission risk can still be used to argue that the bite constituted aggravated assault.
Are Teeth a Weapon?
One of the more contested questions in biting cases is whether teeth qualify as a “deadly weapon” or “dangerous instrument” under state law. It matters because weapon involvement is often what separates simple from aggravated assault.
Courts are genuinely split. Some have ruled that teeth are part of the human body and cannot be classified as a weapon under statutes written to address knives, guns, and other external objects. A Louisiana Supreme Court decision held that “teeth and fists are not dangerous weapons” under the state’s criminal code. Other jurisdictions take a functional approach: if the body part was used in a way that could cause death or serious injury, it qualifies as a dangerous instrument regardless of whether it is attached to the defendant.
Where a court lands on this affects sentencing dramatically. If teeth qualify as a weapon in your jurisdiction, a bite causing significant injury can be charged much like a knife attack. If they do not, the charge tends to stay at a lower level even when the injuries are severe.
What the Penalties Look Like
Simple assault charged as a misdemeanor typically carries up to one year in jail, plus fines, probation, and possible community service. Exact amounts and probation terms differ significantly from state to state, and courts weigh the defendant’s criminal history, the circumstances of the incident, and the victim’s injuries when sentencing within the available range.
Aggravated assault charged as a felony opens the door to prison time measured in years rather than months. Ranges depend on the jurisdiction and felony classification, but sentences of two to ten years are common for mid-level felony assault, with the most serious classifications carrying potential sentences of 20 years or more. Felony fines can reach $10,000 or higher, and courts frequently order restitution to cover the victim’s medical bills, lost income, and related expenses.
A felony conviction also carries lasting consequences beyond the sentence itself. Under federal law, criminal convictions can appear on background checks indefinitely, with no time limit on how long consumer reporting agencies can include them.3Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports A violent offense on your record can narrow your options in healthcare, education, childcare, and any field requiring a professional license, and licensing boards can act on the underlying conduct independently of what happens in the criminal case.
When Self-Defense Applies
The most common defense in biting cases is self-defense: the person bit their attacker to escape or stop an imminent threat. Self-defense works as a complete defense to assault charges when the defendant reasonably believed they faced imminent harm and the force used was proportional to that threat.4Justia. Stand Your Ground Laws – 50-State Survey
Proportionality is where these cases get difficult. Biting someone’s arm to break free from a chokehold reads very differently from biting someone’s face during a verbal argument that turned physical. Courts ask what a reasonable person would have done in the same situation, and they look hard at whether the defendant had other options.
The duty-to-retreat question also matters. At least 31 states have “stand your ground” laws that remove any obligation to retreat before using force in a place where the person has a right to be.5NCSL. Self-Defense and Stand Your Ground In the remaining states, courts may consider whether the defendant could have safely walked away before resorting to physical force. The defendant has to present enough evidence to make the self-defense claim credible, and once that threshold is met, the prosecution must disprove it beyond a reasonable doubt.
Civil Lawsuits Are Separate From Criminal Charges
Criminal charges and civil lawsuits run on separate tracks. A victim can sue the person who bit them for damages whether or not criminal charges are filed, and the standard of proof is lower in civil court. Instead of “beyond a reasonable doubt,” the victim only has to show it is more likely than not that the defendant intentionally caused harm.
Compensatory damages cover medical bills, surgery and rehabilitation costs, lost wages, and ongoing treatment for scarring or infection. Courts can also award damages for pain and suffering, emotional distress, and loss of quality of life. When the defendant acted with particular malice or recklessness, punitive damages may be added.
Most bite cases settle before trial. The physical evidence involved (photographs, medical records, dental impressions) leaves defendants with limited room to dispute what happened, so negotiations tend to focus on the amount rather than liability.
What to Do After Being Bitten
Biting cases produce unusually strong physical evidence, but that evidence deteriorates fast. What you do in the first 24 to 48 hours largely determines how viable any legal action will be.
Get medical attention right away, even if the bite looks minor. Human bite wounds carry high infection risk, and medical records created shortly after the incident become critical evidence. Ask the treating physician to document the wound’s location, size, and depth, and to photograph it from multiple angles. If there is any concern about disease exposure, discuss testing with your doctor.
Report the assault to law enforcement as soon as possible. Give a detailed account, identify witnesses, and share any evidence you have, including your own photographs, text messages, or video. The police report creates a formal record that both prosecutors and civil attorneys will rely on. Prompt reporting also preserves eligibility for state victim compensation funds, many of which require the crime to be reported within 72 hours.
Victims can also seek a protective order. The process generally involves filing a petition with the local court describing the assault and any ongoing threat. Many courts issue a temporary emergency order the same day, with a full hearing scheduled within about two weeks to decide whether a longer-term order is warranted. Consulting an attorney early is worthwhile because biting cases involve overlapping medical, criminal, and civil issues, and the deadlines for taking action are shorter than most people assume.
